The hole looks like it's for a set screw to me, but I agree the cap is just a decorative cover. Not sure what this would be used for though as I don't understand what function a collar and cap like this would do mechanically.
Edit: I see OP mentioned the holes don't go through so you're right they'd be for some special tool.

The indentions on the side are for a spanner wrench to tighten this nut onto a threaded rod. The top is a decorative cover.

Does the "lid" screw in or snap onto the top
Edit: the hole in the side (tiny hole) should also have something to screw into it

The lid screws in.
There are three holes equidistant around the perimeter. They do not go all the way through.

Really? Then my guess is those may be for a tool to hook into for turning. All in all it looks like something pressure line or liquid line related

i saw something like this once where it connects a tank of carbon dioxide to a sodastream type of drink bubbler.

Looks like a spanner nut and the cap appears to be a jam screw to lock it in place.

I think I found the screw plug.

Need to see the bottoms of those pieces.

Kinda looks like something to adjust pressure but I'm not sure.
