The cap (14) when fitted to the hub (13) has its skirt surrounded and thereby protected by the walls of the projecting hub portion. Openings (28) in the projecting hub portion are provided to allow the insertion of a hand tool for manually removing the end cap from the wheel hub. Desirably the cap (14) is secured to the inside of the hub by means of an interference fit.
