Handcuffs, fetters (8)
I believe the answer is:
manacles
This clue is a double definition.
'handcuffs' is the first definition.
('manacle' can be a synonym of 'handcuff')
'fetters' is the second definition.
(manacling is a kind of fettering)
(Other definitions for manacles that I've seen before include "Handcuffs" , "Fetters for the hands" , "Shackles for the wrist" , "chains" .)
