France : Army-style Flaming Grenade Chromed Belt-buckle.

Chrome finish belt-buckle with a separately applied flaming grenade emblem. No makers marks. This is in a French style but could equally be Belgian, Dutch, etc.
The buckle measures 55mm across x 53mm high and would fit a 50mm wide belt. The reverse has two securing bars.
I'm not sure exactly what this is !....does anyone know ?
Very good condition.
