Abstract: A windshield wiper comprises a pressure-applying superstructure and a squeegee assembly releasably mounted on the superstructure to permit replacement of the squeegee when worn. Releasable retaining means comprise a projection on one of the superstructure yokes adjacent to an endmost pair of the claws thereof that retain the squeegee assembly and a cooperating recess on the backing member of the squeegee assembly. The retaining means thus uses the flexibility of the backing member to provide the necessary retention. The projection may have a ramp shape to facilitate the latching action as the squeegee assembly is mounted.

Abstract: The invention provides a retainer clip for holding the backing member of a windshield wiper assembly against longitudinal movement in the claws of a superstructure in which it is mounted. In a first embodiment a claw-like body has a resilient tongue formed on its upper wall by two parallel slots, the tongue having on its underface a projection that cooperates with a recess in the backing member to retain them against relative movement. A longitudinally-extending transverse flexible integral arm has a hook portion at its end that can embrace a superstructure mounting claw, so that the claw is trapped between the clip body and the hook portion against longitudinal movement, and the backing member is thereby retained in the superstructure.
