13 pin car socket help needed please?

[TerryIvybridge]

Trying to replace a 8 year old one, the flap springs busted. Just need help parting the outer from the inner on the old one?

There are various different designs of socket. It would help if you could supply a photo and the name of the manufacturer and, if possible, even the part number which is often moulded in the assembly.
