This is a cross-reference - you need to look at another numbered clue (in this case, clue 15) to understand how this clue works.
Look at clue 15 in your puzzle - it will either provide the definition for this answer, or there will be some connection between clue 15 and this one that helps you solve it.
Answer: TIES | This clue refers you to clue 15, which presumably provides either the definition or wordplay needed to arrive at TIES (things that bind or connect, or neckwear, or draws in games).
