I’ve had this part stored in my bedside drawer for years and I can’t remember what it’s for.
My best guess is it’s from an overlocker that I no longer have(?)
SOLVED: It’s a hinge cover for a fridge freezer set that clips together to look like one large machine. Thanks to everyone that contributed.
I think it looks like they hose locking fitting for a dishwasher, I used to be a white goods repair man, horrible things to get back together after replacing inlet and drain hoses…
