How to make such cables?

Question

Unity

Hello! Can you please tell me how to make cables like in Occupy Mars The Game?
Here is an example: https://www.youtube.com/watch?v=gHLyrjy5Egc
TIMECode: 11:18 - 11:52

This is not a "task", just tell me how to implement such cables so that they are laid when you carry them, and they could end. And, if possible, how to do cable physics without object connection in Unity. And tell me, will the cable model with bones fit, or will it look creepy?

Thanks in advance!
