Rear indicator retaining clips????

Only a small one! Does anyone know wher i can get the square black plastic clips that go into the bodywork and retain the rear indicators - think I've swept them up and thrown them out with all the used wet and dry paper :-(
Looked all over but no joy - If all esle fails, i'll have to get some metal clips, but would rather have the originals.
Cheers
