Unkown ordnance relic?

[Normandy1944]

A friend of mine found a strange object during metal detecting.
It looks like some kind of ordnance, because it has a safety pin inside. (if it is one)

I was wondering if you could help me out with finding out what kind of object this is.
Somehow, I can't post pictures so here's a link to the pictures on another forum:

Looks like a weight for a kerosine roof-lamp.
