Duo hired band (8)
I believe the answer is:
bracelet
'band' is the definition.
(bracelet is a kind of band)
'duo hired' is the wordplay.
'duo' becomes 'brace' ('brace' can be a synonym of 'duo').
'hired' becomes 'let' (I've seen this before).
'brace'+'let'='BRACELET'
(Other definitions for bracelet that I've seen before include "Ornament - handcuff (slang)" , "Ornament worn on arm or wrist" , "Arm band" , "Personal ornament" , "Ornamental wristband" .)
