Is it possible to create a knot that is stable/locked when the rope is stretched? When the tension is relived the knot should open.

$\begingroup$ For two ropes tied together? Or a single rope? Seems like any knot in any single rope fits this if the rope material is smooth enough for it to happen in any one case - no rope knot is stable/locked without tension, just a tangled rope. Tension forms the knot initially and tension between the touching surfaces of the rope maintains it/keeps it stable. TL;DR; Please clarify, I'm confused $\endgroup$– TCooperApr 16, 2020 at 19:55

$\begingroup$ Would a Prusik Loop work? en.wikipedia.org/wiki/Prusik This needs two ropes though. $\endgroup$– UnidentifiedXApr 17, 2020 at 0:30

$\begingroup$ The mariners use the bowline knot. It is easy to info it when it is not in tension. $\endgroup$– Alain RemillardApr 17, 2020 at 16:46
