MK2 mystery part identification

I’m re-installing the interior in my MK2 after replacing the headliner and refinishing the wood. I have a small part that I can’t identify. It’s a small tapered, split collet, see photo.

Could someone identify this and where it lives? Thanks
Darrell

I’ll hazard a guess:

It’s too small to be from the fan motor, and that is larger than a penny, far away from the headliner, and is anyway a finger collet arrangement.

But it might be the clamp from a read view mirror, which you would have removed to redo the headliner and wood.

That’s it! It fits on the mirror stem. Thank you much!

It’s a valve lock collet.

I should have said if there’s two it’s a valve lock collet
