I took inspiration from Alan Lee lately, trying to find solutions for a loop knot that involves a bight through the nipping loop.
The idea was to find a secure knot that unties easy and in fewer moves.
I’m sharing here the two that seemed to stand out from what I found, unfortunately I haven’t properly loaded either yet.
I hope you find time to tie and appriciate untying )
Nr. 1.
Very simple post eye tying… with a bit of practice 
there are many variations of the base Idea, all seem to be secure knots. To me the one shown below stands out.
It involves two collars that I believe stay loose in loading.
The half twist of the bight that reenters the nipping loop, creates the particular geometrie of this version. It is more balanced and compact, and keeps the nipping loop from moving. It is remarkably hard to shake open.
The ease of opening and untying seems outstanding to me.
have you tied it yet? can you find flaws?
Nr 2.
This appeared when searching for a knot that releases by undoing just one tuck of the tail, while being reasonably secure still.
If this was considered original, I would call it “clapper loop” for obvious reasons )
There are many variations on the base idea. The one that seems to stand out is the slipped version, shown below (tail down, towards the loop as shown. Release by pulling both legs and the tail! )
… do you agree this Knot is a clear “step up” compared to #1866/1874?
Also it has a potentially interesting property when tied in ropes with low friction:
If the nub is held accordingly the nipping loop can slide remarkably freely up and down the standing part.
Hi Andreas
When i first saw the slipped version shown at reply#2, in fourth image, it quickly draw my attention, and the so called “clapper loop”, has been sounding the alarm ever since 
:).
You have come up with a way-out idea, teaching all of us, how to lock two returning line bights, around a nipping loop, stabilising the loop in a solid way, at the same time.
In short, a few words about the tying method........
[i]1. Push a bight through a nipping loop.
Fold the bight over the nipping loop’s crossing point.
Pull the nipping loop up through the bight, creating a pocket.
Form a second bight with the remnant tail, and pass it through this pocket (nipping loop).[/i]
I’ll have to point out that it’s this second bight that locks down the system in a myrtle-like way.
Does it qualify as a bowline then?
Hard to answer, as there is no direct SP collar capture, but a bight which takes the form of a collar (or two) , whose both leg continuations are clamped by the nipping loop.
For sceptics that question the security of a slipped version, i would pinpoint, the effectiveness of this dual bight, returning, nipping loop binder, within the boundaries of which the two main lines are loaded, along with the four rope diameters inside the nipping loop!!!
How cool is to pull the tail and end up with an unknotted rope in your hands? I’m not sure if there’s a bowline-like loop with such property.
Loading it with a rope with known limits, it didn’t gave me a hard time to untie.The two ears of the first bight (collars) appear to be manageable at heavy stress.
Given, that it won’t develop deformation or jamming issues with EN rated ropes (such us choking the slipped bight at heavy loadings), i would be unfair if i told you that this is an interesting attempt that calls for further investigation.
It might be way more than that!!
Image= Z ans S based clapper loop from left to right.
So cool to see the knot tied and shown again, thanks a lot for input again.
And yes the collars “of a different kind” are intriguing, a bit strange (not familiar), and work somehow very well )
Opening with one tuck while holding the loop, seems to differ in ease. Depending how the second bight is turned:
The tail on the side of the loop (my picture) opens more easy. Tail on the side of the SE (your picture) less easy to pull open.
I believe the knot deserves a thousand illustrations.
Some more clarifications about the tying method in more detail, to avoid any misconceptions.
[i]
It’s easier to work from the detail view of the knot.
This maneuver captures the returning eye leg with the tail, maintaining a continuous line, between the returning eye leg and the collar around SP.
Fold the bight over the nipping loop’s crossing point, and pull the nipping loop up through the bight (third image).
Form a bight with the tail and reeve it over the first bight and through the nipping loop.
Cinch the collars and dress the knot properly.[/i]
Great pics Kostas, thanks.. much more clear now.
From there questions come up, about the details of this version of the base idea.
One of them is the tail crossing or not, the incoming leg, that you mentioned in point 2.
(1st pic below)
… whether the incoming leg forms the upper or the lower collar.
(2nd pic below)
(The pictures show the version non slipped for easier view)
the Tail crossing the incoming leg seems to be more secure, no crossing seems more compact
Generally the incoming leg forming the upper collar first seems to be better, but I couldn’t say why. Bit easier to tighten maybe…
Which of these options would have the edge?
liking it, Andreas !
and super pics and commentary thanks Greg ! (Knots_Greg)
clapper loop 2024
i’m a fan of the slipped version loop
(at a glance it has elements with partial resemblance to riggers bend)
Thanks Alana )
After tying this knot many times over many weeks. My favourite version was tail crossing the incoming leg + incoming leg forming the upper collar around the SE first.
.. which is the version beautifully shown in Reply #5
And I started to form the slip in a particular way to make opening even easier:
light green rope on the left. Tail side of the slipped bight down
Appeared AND was recognized as worthy --captured!
In contrast ::
My “Quick8” EK is something that I tied LONG ago
–heck, maybe even making an image of the state–,
but not until decades later did I realize that I could
STOP at that point (!), no need to U-fold that tucked
RELeg Tail back into the Fig.8 base for security!
It (Q8) was smack before me yet unseen.
((Q8 = F8 base, RELeg return through 8’s U-turn
as for common Fig8 EK, then simply reeved out
through other “loop” of F8 going OPPOSITE
direction (“up & out” =“opp.” to “down & out”)
to S.Part and trapped between it and the side
of this “loop” that the S.Part will bear into
–which it does adequately to nip this so
minimally reeved Tail !
For the verbally challenged, see TreeSpyder’s image here :

))
Funny how these things can happen; and somewhat
challenging to a preference to making a thorough,
rigorous search through knot forms --which can seem
tedious, at least to me .
There are many variations on the base idea.Yes, and they can keep coming (even by inspiration w/o the rigorous search)!
What stands out for me is that one can reeve the
RELeg U-fold through the nipping loop from either
“front” (like BWL #1010) or “back” (like “Bollard loop”) side
–nicey accommodating of this variation!
Also it has a potentially interesting property when tied in ropes with low friction: If the nub is held accordingly the nipping loop can slide remarkably freely up and down the standing part.This can occur in #1010, w/o holding anything, just loading. And it's a justification for those knots w/SPart structures that are move involved before sending out the Outgoing Eye Leg. (I've not seen any testing to show if such slippage amounts to much (of distance or strength) in [u]dynamic[/u] loading --i.e., which might be too sudden to get fast-enough slippage!?
So,
... whether the incoming leg forms the upper or the lower collar.In the "upper"=>S.Part-side case there can be less influence against the S.Part's nipping turn curvature; in the latter case, there might be some help to grip S.Part in the turn and resist the aforementioned slippage!?
Sooo, seeing some few (say, 4) aspects of the structure
to vary, and in combination, you get 4xNxY = LOTS of
knots to consider (or –– illustrate).
All this knowing that in SOME cases it’s “6 of 1,
half-dozen of another” but in others "OHHHH,
my, THAT was a surprise (in risk) (e.g., the
potential spilling of a ring-loaded #1010 BWL!)
The idea was to find a secure knot that unties easy and in fewer moves.I see too much implication (in knots literature) that merely "slipping" (finishing w/Tail tuck of a U-fold) will produce an easily untied knot :: in fact, often --e.g., in a tightly set Constrictor knot-- the knot will be set hard/tight, and it will take noticeable effort to pull even the Tail's parallel leg of the slip-tuck into movement, and THEN maybe no such luck in getting the U-fold apex to come through --that that U-turn will be in rope not happy to flex SO much, and effectively work like a stopper.
So, if indeed quick-release is needed, aim to have
the Tail’s slip-tuck made where compression of
parallel sides is NOT needed, and the binding
pressure is slight.
thanks for the notice Kostas, Xarax!
this came before I started reading here.

maybe Alan Lee can add here, the old thread is hard to read with photos being compromised.
… which Knot is mentioned and pictured in Reply nr1. ?
yes! actuallly I think anticipating what you proposed helped me rediscover it
Knot Nr. 1 exemplifies the same idea: how to have low friction when taking out the tail. (this is a “nice to have” generally, but when slipped in particular)
what’s left is to see how easy the tail comes out
AND
how secure the knot is at he same time. Alans slipped loop Knot hits a sweetspot?!
According to the link that was included at reply#10, it appears that Alan Lee had been experimenting with the clapper loop in the past.
In fact, i barely make out from the attached images that he has strained the knot with a load of 4000 lbs = 1824 kg, which is a very decent level, to draw some conclusions about the knot response.
Maybe Alan has more info, and is able to enlighten us to a greater extent, about the knot’s jamming profile?
Hi guys,
Most of the time I do have a copy of the knots that I have posted,
but sometimes I do forget to keep it and will try to find it. Thanks.
Andreas Congratulation, you have created a very nice, well secure bowline variation.
It has three diameter ropes in the nipping loop, the tail collar lock the nipping loop Well,
just by looking is good enough to tell it is jam proof and easy to untie. I see no flaws at all.
The new Bowline variation is hard and harder to come by. Excellent work.
Great work on the quick release loop too, When the loop appears, to see it is easy,
to create the loop, it is a totally different story.
So far, I have only found these pictures. Hope it helps.
Great work on the quick release loop too, When the loop appears, to see it is easy, to create the loop, it is a totally different story.Hi Andreas, My poor English, and what I wrote above, may miss lead peoples to think the wrong way. What I mean above is just to let our reader know it is not easy to create such a wonderful loop. We have failed many times and after many many attempts with some luck, we got it built. I have no doubt about your ability, I trustfully believe you have created this loop too. Enjoy your new knots. Also thanks Greg and Dan' input and participation. alanlee.
Thanks Alan, your english is just fine, I understood like this.
Thank you for your comment on Nr 1.
Actually in this particular case, things we’re more complicated. I tied the “simple lock” that you shared some time ago, before I saw you doing it, but did not pay much attention. When you posted simple lock, I got interested again, which lead to my own challenge to “use a tail bight through the nipping loop well!”.
So all this tying that was needed to arrive to Nr 1. And Nr. 2 I did with your support, not by myself
See below another result, from your idea. It can be compared with the EBSB bowline.
Not so original, but I like the way it ties, and tightens and unties.
And how secure it seems to be. Nice candidate for harness tie in?!
I tried to find the knot that Xarax was refering to in his first reply. #1.
I had no success…
" Lee s quick release adjustable loop.jpg. "
You know which knot was meant?
i tried tying the clapper loop upside down or mirror image or left-handed or something,
and got this mis tye,
but the back of it features an aster shape which always appeals to my eye;
and it still seems functional
Alana, it’s hard for me to folllow all the rope components routing in your core, more details are required, perhaps a loose knot or a more distinct illustrated form.
Without being absolutely sure, dare i surmise that you have probably locked the nipping loop, instead of locking the first inserted bight (white arrow in the attached image).
Such maneuver creates a completely different knot, but i need to see more detail for a comprehensive view about its performance.
So, with some reservation, i would claim that the clapper loop was probably mistied.
Lucky for us, Xarax tends to keep a record of good knots. See second attached image.
About the knot at reply#16, i reserve some comments for another reply.
