Unknown part

[Sparkyme24]

I’ve found the below part under the passenger side seat. Not sure what it is. Any idea?

It’s a very small chock to stop your car rolling away when your handbrake fails.........

Seat runner end cover?
Is there a part number moulded onto the part?

Is it the same width as the seat belt ?

It's a spare in case you lose the other one.

It looks very much like the limited edition Mercedes Benz truffle shaver. A highly sought after piece which had its own storage compartment directly underneath the passenger seat.

Any part numbers on it?

Is it the same colour as any of the other plastic trim?

What car is it? '2015 Saloon' doesn't really give enough information to go on...
