Feature framing ring and choker (5)
'choker' is the definition.
(a noose chokes someone)
'feature framing ring' is the wordplay.
'feature' becomes 'nose' (I've seen this before).
'framing' means one lot of letters goes inside another (inserted letters are framed by the outside letters).
'ring' becomes 'o' (letter resembling a ring).
'nose' placed around 'o' is 'NOOSE'.
'and' acts as a link.
(Other definitions for noose that I've seen before include "Scaffold rope", "old execution method", "Loop with sliding knot in a rope", "Loop in rope that tightens when pulled", "Circular loop".)
