Rock-to-Lock Connection Arm-To-Blade Abstract Connector apparatus is provided for permitting rapid connection and disconnection of a wiper blade from a wiper arm. The blade portion of the connector includes a pair of spaced apart parallel slots. To accommodate dif- ferent styles of wiper arm ends, two longitudinally spaced pins are provided on the blade. One of the two pins is used with an arm end having two parallel spaced tabs with for- wardly facing pin slots and the other pin is used with an arm end having two parallel spaced tabs, forwardly facing pin slots and rearwardly spaced guide portions. Both of the last named two arm ends have structure for retaining the blade on the arm end even when the blade and arm are lifted from the windshield. In an additional embodiment, one of the two pins is removable to accommodate attachment of the side pin of a side pin style connector. Since the arm is secured to the blade along two transversely spaced planes, the chances of rollover of the blade relative to the arm is minimized.
