It appears to have fallen over and metal fatigue has set in at the top just below where the rusty bolt attaches it to the seat. It is made of a non-rust type of metal and painted blacky-green old style. It doesn't look weld-able...

If the metal shows no rust at all, the chances are its made from an aluminium alloy. Although it is possible to weld aluminium, it really needs a specialist to do this. There isn't any adhesive good enough for this application, unfortunately.
