Hand shackle (7)
I believe the answer is:
manacle
'hand shackle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for manacle that I've seen before include "item restricting movement" , "Shackle on the wrist" , "restricting at the cuff?" , "Handcuff" , "Curb" .)
