A shield for an automotive compressor clutch assembly is disclosed in which a resilient hollow part attaches to the rotatable clutch pulley by means of an annular lip located along the inside of the hollow part and an annular groove located along the outer rim of the pulley, thereby covering the outside surface of the pulley together with the clutch mechanism located adjacent thereto. A cooperating notch and land arrangement prevents relative rotational movement between the shield and the pulley.
