Not so mystery parts

[noodles.21]

I bought this mini reg off ebay and was thinking about hooking up mini keg and popping it in the fridge. The lower one i get is the for the sodastream and i was hoping to just clip onto the keg with the output. Naively, I thought the connections were pretty standard but when i took this down to the local brew shop they couldn't find anything to fit this attachment.

Could anyone help with identifying or even linking what I would likely be looking for to connect to this minireg?

Cheers

Its a MFL fitting, clever brewing as the example, Kegking, Cheekypeak, Kegland etc all stock them but your local should as well
