Abstract: A plurality of axially extending resilient prongs on a wheel cover, the free ends of which extend through prong receiving holes in the mounting bolt circle area of a disk of a vehicle wheel. The prongs are bifurcated with a pair of spaced apart axially extending fingers with an integral diagonally and axially extending web therebetween which resiliently biases cam surfaces adjacent the free ends of the fingers. The cam surfaces engage the inner edge of the prong receiving holes to abut the free ends of the prongs with the mounting surface of a hub on which the disk is secured to firmly and tightly retain the wheel cover on the wheel.
