Abstract

A windshield wiper for motor cars with a wiper arm which terminates at its free end in a U-shaped hook, while a connecting piece articulated to a wiper blade and preferably consisting of plastics is slidable and anchorable between the members of the U. In order to ensure a play-free connection even in the longitudinal direction of the wiper arm and/or wiper blade, a fastening yoke, which is articulated to the connecting piece at a pivot axis thereof, in its closed position, engages externally and clamps around the U-shaped hook and tensions the connecting piece towards the wiper arm.
