The break is quite close to the original connector, I originally thought it would be too short once I had paired back the cable but looking again I think I should be ok. Its hard to tell what connector they are using as there is no marks at all on the plastic or metal apart from a siemens printed logo on the metal casing. The closest thing I can find is by a company called Lapp. If it is a Lapp I will need to buy a new 12 pin insert and crimps to go along with it, at £5 it shouldn't break the bank and much better than buying a complete new metal connector.
