what are these babies called?

[integerspin]

I couldn't find any hence the sketch. My matsuura had these soft clear rubber[silicone?] boot's over ring terminals that were bolted together. I have searched all the cable management and terminal sites I can find and not come across anything like them.

I have seen them advertised in one of the industrial heatshrink suppliers catalogue, I forget which now, if I come across it I will post it.
It could be either Panduit or Raychem?
