Link or connection (3-2)
I believe the answer is:
tie-up
This clue is a double definition.
'link' is the first definition.
(I've seen this before)
'connection' is the second definition.
(I've seen this before)
(Other definitions for tie-up that I've seen before include "Link, connection" , "Link (between companies)" , "affiliation" , "Telecoms link" , "Bind" .)
