I believe the answer is:

snug

I'm a little stuck... Click here to teach me more about this clue!

'cozy' is the definition.
(I know that cozy can be written as snug)

I can't explain the rest of the clue.

(Other definitions for snug that I've seen before include "Well protected or concealed" , "Bar parlour - comfortably placed" , "Cosy and comfortable" , "Small bar in pub - warm and comfortable" , "Close-fitting and cosy" .)

I've seen this clue in The Times and The Sunday Times.
