Mystery connector brand??

[Camberwell Canary]

I have an immersion chiller with a 3/8" hose and brass connector attached to it. It is a common brand, but not labelled. I've seen them before and on this forum. Please could someone list the common brands of hose quick connects? It's not hozelock; think it might be German? It has two brass hook type things diametrically opposite each other which clamp it into place when attached to another connector.

Will send a photo when I get home.
