Knot with loop that tightens (5)

I believe the answer is:

noose

(Other definitions for noose that I've seen before include "Loop with sliding knot in a rope" , "Hanging loop in rope" , "Loop at the end of a rope" , "Fatal device" , "Scaffold rope" .)

I've seen this clue in the Sydney Morning Herald.
