The semi-circular flanges that hold the cable tensioning devices of a bicycle's gear changing system firmly against the curved frame tube of the bicycle. Usually silver incolour, and made from a hard, metallic alloy.
My new gear changers were supplied without golliwogs, so I had to scrounge for an old set in the cycle store's workshop.
