Connects (4,2)
'connects' is the definition.
('link' can be a synonym of 'connect')
This is the entire clue.
(Other definitions for links that I've seen before include "provides connections to other websites" , "Type of golf course" , "Where golfers play" , "course for sportspeople" , "Golf courses close to the sea" .)
'connects' is the definition.
('tie in' can be a synonym of 'connect')
This is all the clue.
(Another definition for ties in that I've seen is " Secures by a 8 Across".)
