Rather surprised at the responses.
But what comes to mind is that many fishing loops would work like magic. I like the Double for slick cord
Somewhere the criterion for quick-tying was lost,
and, frankly, I doubt this is all so secure in lesser
lacing (and quite expensive in material)!
Any knot can be undone given enough effort ...
Good luck w/those rosy glasses, mate! Apparently, the term
"welded" hasn't come your way w/knots; it has, for many.
My first thought ran to a
double overhand eyeknot(i.e., like the
overhand loop but w/a
strangle (or more));
that's quickly tied and firmly set. Your idea is along these
lines for a component, and should suffice.
Looking to fishing knots for
inspiration, I take the
old favorite,
the blood knot, and work an eyeknot
out of it, as follows (with orientation of SPart running
away leftwards, eye to-be-formed at right, horizontally
disposed working) :
1. make an ample 270deg anti-clockwise loop, and form
a bight --the size of desired eye-- at the closure of this
loop (i.e., where it crosses the SPart) and have bight
cross OVER SPart; a bit of tail stays above SPart, and
to left of other bight leg;
2. Wrap tail back around SPart to up now on right of
bight-crossing.
3. Now, this big loop (not the eye bight, but the first-formed
ample loop) will be material you can easily increase/decrease
with which to essentially make a
common whippingwrapping of the SPart & eye bight with, turning it
back-downUNDER-forward-up ... a few times;
4. Then haul the SPart to set this whipping wrapping
tight against the eye-bight's single turn.
(The general idea came to me from seeing in
Barnesthe joining of a short bight's tails to a line using the
blood knot working --2 strands vs. 1. It occurred
to me that were one to fuse the single-line's (SPart's)
tail to one of the bight's tails, you'd have a normal
eyeknot (with one tail), TIB (Tiable Inthe Bight), too!)
The same knot could be tied beginning at though to
tie a
double strangle knot and just modifying the
finish to be with the one-turn-secured end bight.
Then, again, a simple,
overhand loop is considered
pretty jamming --the tying is simple, you just need
to give it a hard setting, well beyond what kids will
have means to untie.
