a friend gave it to me ±15 years ago. He thought it was impossible to get the ring out. Maybe it’s faulty and they cut the rope shorter than they should have.
We don’t know what this is 🤷
a baby toy?

The rope does not go though the ring. This ring is loose, yes it’s a puzzle

Ring and rope puzzle. Tons of models of these, though this one apparently has a pretty high difficulty rating
Knowing these you’ll probably have to thread the ring through the slit at least once.
I bet the real trouble will be once you solve it remembering how you did it and getting the ring back on.
Not just the ring, also the disc.
Edit: I’m not good at visualising, but it looks like mive the ring to the left over the slit, put the disc through the slit and then move the ring back.Second edit: probably not.
Disentanglement or Tavern Puzzle
Yes, it’s a puzzle. The aim is to get the ring off. Had one very similar at home when I grew up.
The trick to knots is that only two kinds of them exist in 2D. The knot that is a knot and the one that isn’t. To transform any knot into not a knot you only need to cross the rope through itself once. Ie cut and splice.
If you want I can give you abstract tips. But I think my hint was already close to telling you the solution.
Insanity it is then.
Cut the rope. Got it!
I’ve got a similar one, maybe the same puzzle, that’s on my desk. I’ve not figured it out yet.
Looks like a topological untangling puzzle.
First one looks kinky 👀
They’re all variations on this (no spoiler)
