Chap carrying can over form of restraint (7)
I believe the answer is:
manacle
'form of restraint' is the definition.
(I know that manacle is a type of bond)
'chap carrying can over' is the wordplay.
'chap' becomes 'male' (chap can mean a man).
'carrying' is an insertion indicator.
'over' indicates an anagram.
'can' anagrammed gives 'nac'.
'male' enclosing 'nac' is 'MANACLE'.
(Other definitions for manacle that I've seen before include "Curb" , "Hand/ankle restraint" , "Fetter" , "Shackle on the wrist" , "restricting at the cuff?" .)
