Binding bandage (8)
I believe the answer is:
ligature
'binding bandage' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ligature that I've seen before include "Thread used by surgeons" , "Something used to tie" , "link" , "Thread for sealing blood vessels" , "Cord used to tie off in surgery" .)
