A detachable wheel trim for a vehicle wheel, having anchorage hooks for attachment to the wheel, operable from the external side of the trim. In one form three anchorage hooks are connected to a triangular arrangement of three resilient steel links fitting over a triangular cam connected to a rotary knob on the external surface of the trim, so that by rotating the knob and the cam the three links are bent outwardly to cause a resilient inward force to be applied to each hook, alternatively the three links may be combined into a continuous hoop, and the rotary triangular cam may be replaced by an axially movable cam. Two or more pairs of parallel links may be used instead of a triangular system and in place of a cam the links may be operated by levers connected to a rotary or axially movable central shaft connected to the external knob.
