Hi,
Connectors like this tend to be manufacturer specific, they are made only for a specific piece of equipment. Chances of finding one elsewhere are slim. I think your best bet would be to contact the local service agent for the equipment. . . Or maybe see if you can buy another camera the same (ie. one being sold spares or repair) for example on ebay, or local junk shop.
In fact if you're willing to spend a few pounds, you can get some really small CCD camera units on ebay quite cheap.
