Adjustable rope loops (6)
I believe the answer is:
nooses
'adjustable rope loops' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nooses that I've seen before include "Loops in lariats" , "Loops for the hangman" , "Rope loops with tightening knots" , "Loops in cowboy ropes" , "Running loops" .)
