The French friend comes back for part of jacket (5)
I believe the answer is:
lapel
'part of jacket' is the definition.
(I've seen this before)
'the french friend comes back' is the wordplay.
'the french' becomes 'le'.
'friend' becomes 'pal' (pal is a kind of friend).
'comes back' shows that the letters should be reversed in order.
'le'+'pal'='lepal'
'lepal' reversed gives 'LAPEL'.
'for' is the link.
(Other definitions for lapel that I've seen before include "Part of a suit jacket" , "Folded-back part of coat" , "top of coat" , "Folded flap at front of jacket or coat" , "Folded back part of jacket" .)
