Restrictions Charles imposed outside home (6)
I believe the answer is:
chains
'restrictions' is the definition.
'charles imposed outside home' is the wordplay.
'charles' becomes 'chas' (shortened form).
'imposed outside' means one lot of letters goes inside another.
'home' becomes 'in' ('he's home' can mean 'he's in').
'chas' enclosing 'in' is 'CHAINS'.
(Other definitions for chains that I've seen before include "Restriction" , "Sequences" , "help to pull?" , "Fetters" , "Cash in for manacles and irons" .)
