Tubing for cable routing. Push this clear tube over one cable end securely (use a small amount of tape to keep on if long cable). Pull cable out of machine which will pull this clear tube into the machine in its place. Then reverse to pull final/new cable into the machine while pulling out this clear tubing.
Do not tape over bulb/ball of cable end fitting which will enlarge the joint and possibly get caught inside of the machine.

Sold per foot (you will need this tube to be 4 feet longer than that of your cable being changed).
