Abstract
A windshield wiper (10) is provided with parts for connecting a plastic windshield wiper blade assembly (11) to a wiper arm (14). The connecting parts include a side pin (30) carried by the wiper arm (14) having a keyway (75) at the end (71) thereof and a pin-receiving aperture (42) defined in a yoke (17) with a U-shaped spring (50) extending in chordal fashion through the aperture (42) and a key (66) projecting into the aperture (42). When the side pin (30) is fully inserted into the aperture (42), spring portions (57,58) will releasably seat in a reduced diameter constricted segment (69) of the side pin (30) to secure the yoke (17) on the wiper arm (14). If the side pin (30) is not fully inserted, engagement of the key (66) and the keyway (75) will lock the yoke (17) and the wiper arm (14) in skewed relation to prevent proper contact of a wiping element (27) carried by the yoke (17) with a windshield (16).
