Repairing PVC cable insulation in-situ

[Nozzle]

What is the best way to repair twin and earth insulation? I'm only referring to the grey outer that has been torn, rather than the brown and blue beneath which is still very much intact. Insulation tape is a bit gash, and the cable is not in the position to be replaced and access is too hard to fit a box unless it's pretty easy to snap together (maintenance free type, of course). Is there a clip-on plastic device that is suitable? I can't thread shrink-wrap over the end which is a shame. The tear is located beneath floor-board level where it comes out of hole from a stud wall.

Self amalgamating tape.

From the sounds of it he wouldn't be able to pass tape around it.

What about a length of split flexible conduit filled with silicone sealant?

Mind you - do you remember the last person we had here who said that a cable sheath was damaged but the cores were fine?

Wrap around heat shrink.
or split a section of oval conduit.

Thanks for the responses gents - I have just got back from the shop laden with some nice amalgamating tape and later on this evening when the work is finished I'll upload the pictures. I might put some spiral wind on afterwards for the belt and braces approach too.

You could also have fitted some kind of enclosure or junction box over it, without actually making any connections.
