What is this?

Was sorting out the front speakers and found this rattling in the driver door.
Any ideas what it is/does. Cant be too important as all is fine but has been bugging me!

Doesn't look like anything I've seen inside a Mk2 door before!

No part number on it?

Is it not a fuse puller?

Fuse puller! Hmm you may be right... Taking a closer look this does seem to be what it could be! I never had one since I had the car. Now.... HOW THE HELL DID IT GET "INSIDE" THE DARN DOOR????
