Tugs for Americans (5)
I believe the answer is:
yanks
This clue is a double definition.
'tugs' is the first definition.
(I've seen this in another clue)
'americans' is the second definition.
(Yank can informally mean someone from the US)
'for' is the link.
(Other definitions for yanks that I've seen before include "Pulls sharply" , "Americans; pulls" , "Tugs" , "Physical jerks" .)
