retie

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for retie that I've seen before include "Link up again" , "Make knot or bow again" , "Bind again" , "make another knot" , "restore connection" .)

I've seen this clue in The Hindu.
