This piece represents an idea to protect any vulnerable point on a cable.

In my specific case, I spliced and soldered a replacement USB-C connector to a USB cable; even though I folded the cable and taped in a way where there is no force on the soldered joints when the cable is pulled, I wasn't comfortable in a weak spot of the cable that is exposed especially during movement / use. So I designed a means to have an additional hard protective cover to go over the vulnerable section.

Basically a tube with a slit through it.
Some things I discovered while making it work.
1) The slit acts as a spring so that it can be closed and compressed around the point of the cable that is being protected.
2) The size of the slit should be slightly smaller than the size of the cable that goes through it.
3) The size of the tube diameter should be about the same size or slightly larger than the part of the cable that got repaired, if possible.
4) That way, the tube can be compressed a bit while fastening electrical tape around it.
