Make off with sailor's pipe (6)
I believe the answer is:
abduct
'make off with' is the definition.
(I've seen this before)
'sailor's pipe' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'pipe' becomes 'duct'.
'ab'+'duct'='ABDUCT'
(Other definitions for abduct that I've seen before include "Kidnap, shanghai" , "Hijack" , "Carry off illegally" , "Take (someone) illegally" , "Kidnap, carry person off by force" .)
