I never got the tools to properly work with one, but they're pretty straight forward. You can probably put a new end on by smashing it into a new connector, but who knows how good of termination you'd get. If it's like an IDE cable, it's just headers and sockets.
Hopefully that's where the problem is. I think I saw something like that on a "make it a 286" chip upgrade. You pulled the 8088 out of the motherboard and plugged it into the board. You could then switch via a toggle switch between your 8088 and 80286. Of course the cable is missing on mine!
