Bits of broken strap (5)
I believe the answer is:
parts
'bits' is the definition.
(I've seen this before)
'broken strap' is the wordplay.
'broken' is an anagram indicator.
'strap' with letters rearranged gives 'PARTS'.
'of' is the link.
(Other definitions for parts that I've seen before include "bits" , "Areas" , "Strap (anag.)" , "Leaves" , "Components of strap" .)
