The problem is the tabs either side, if they are how it is secured, as I suspect, then a normal fork isn't going to work, nor will it be easy to modify any standard fitting. Probably a bespoke part. I would be very surprised if they will sell you just the connector. Probably be a new one of whatever is on the other end !
I think you may well end up having to make one.
