I inherited this utensil as part of a larger cutlery case containing lots of other stuff, all related to the kitchen somehow. I do not know what this is supposed to be for, it might even be part of something else. There is what seems to be a hole for a screw, and a long elongated plastic thing squishes between the metal frame.
To me it looks like this is a grill pan handle.
These are used to lift the (potentially hot) grill pan under the grill. Many are detachable so that the handle doesn't get hot.
There are other that are non-detachable but held in place with a screw. Often people just remove these so that they are easier to store. I suspect you have one of these.
I don't think the other answers are correct. The hook at the bottom would not allow the handle to be bolted to a pan.
It looks more like a detachable handle for a deep fryer. The ones I'm familiar with all have a handle that can easily be detached from the basket so it allows for easy storage. (you can drop the handle in the basket and close the lid)
It can be part of a mess kit, as removable handle of a skillet or food tray.
As mentioned by Darrel Hoffman, you can remove the handle while the pot is over an open campfire.
It is a detachable handle for the basket of a steamer or deep fryer, or possibly a casserole pan. My stove came with something similar for lifting the broiler pan out from under the griddle. If you also inherited a vintage stove or special type of cooker, do a search for accessories specific to that appliance.
