mystery part need help identifying please

[earthwormjim]

Hi, new Aygo owner, first post but visited many times already for info and help.  Can anyone tell me what these are please? From a mk1 Aygo, found a handful of them in the boot but can't see where they go.  Probably really obvious but they might not even be from the car for all I can tell.  They are grey and about 4cm long with some sort of hook on the underside.

Thanks!

A picture of both sides could help.

Don't think they are car related, they look the wrong colour
