Abstract
Abstract A windshield wiper assembly is provided with a wiper blade and a backing strip together with a blade retaining clip engaging the backing strip and connected to the blade to prevent movement of the blade with respect to the backing strip. For this purpose the clip preferably has a portion thereof located between the backing strip and blade and has prongs thereon which project into the material of which the blade is formed. The backing strip and/or the blade or both may b formed of extruded plastic material and in an alternative embodiment of the invention, the wiper blade has an electrical heating element carried thereby, whereas blade supporting members which are detachably connected to the backing strip form part of an electrical circuit including the heating element and blade retaining clip.
