Rope and ring in snout (5)
I believe the answer is:
noose
'rope' is the definition.
(noose is a kind of rope)
'ring in snout' is the wordplay.
'ring' becomes 'o' (letter resembling a ring).
'in' is an insertion indicator.
'snout' becomes 'nose' (informal term for nose).
'o' going inside 'nose' is 'NOOSE'.
'and' acts as a link.
(Other definitions for noose that I've seen before include "Loop at the end of a rope" , "Snare, restraint" , "Hangman's rope" , "form of punishment" , "A loop for the hangman" .)
