Bind damaged parts (5)
I believe the answer is:
strap
'bind' is the definition.
(strapping is a kind of binding)
'damaged parts' is the wordplay.
'damaged' is an anagram indicator.
'parts' is an anagram of 'STRAP'.
(Other definitions for strap that I've seen before include "Parts of a leather band" , "loopy band" , "Beat; securing band" , "Narrow strip of leather" , "Elongated leather strip" .)
