I struggled to keep the PTFE cable in place. I tried many solutions, but none worked.

Finally I made this, and it works fine.

I may want to tight the screws until it starts to stop the cable. Then you release a bit, and you can install it.

I will work on a better solution later.

Requires 2xM3x10 screws.
