Title: Attachment of windscreen wiper blades to wiper arms

Abstract: A pair of molded plastic components are juxtaposed face to face to form a body, U-shaped in longitudinal cross section on a plane perpendicular to the juxtaposed faces and include flanges on the sides thereof. The external shape of the assembled body fits into a U-shaped space defined by the end of a wiper arm of the "shepherd's crook kind". The juxtaposed faces each have formed therein a transverse semi-cylindrical recess. When the sections are arranged face to face the recesses form a transverse bore to contain a grooved pin extending transversely from the side of a wiper blade harness. An internal circumferential projection in the recesses engages the groove in the pin; the flanges engage the side edges of the arm. A pair of resilient detents projecting outwardly from the web portion of the U-shaped body engage the web of the shepherd's crook arm.
