Abstract: A molded plastic slidable latch member for retaining a side mounted wiper blade on a wiper arm having a laterally extending connecting pin is retained within a plastic insert. The rectangular plastic insert is retained between the flanges within a rectangular aperture in the web of a channel shaped metal yoke. Aligned cylindrical projections on each side wall of the insert lie within aligned openings in the flanges of the yoke. Aligned holes extending through the side walls of the insert and the projections serve to journal the laterally extending pin on the arm. Contact at the junction between the metal components of the arm and the metal yoke is precluded. A cover plate on the latch is externally accessible to permit manual actuation of the latch from a latched position engaging the pin to an unlatched position.
