Jack Cap 

A protective sleeve made to go over the "jack" of instrument and other cables to keep them from getting damaged and to maintain sound quality.

I just picked up a new guitar chord and it came with Jack Caps for each end.

Wow, my chord is coming apart at the jack, I wish I had some Jack Caps to keep that from happening.
