ABSTRACT:
A connector is provided between a wiper arm and a wiper blade. The connector includes aligned openings in the parallel walls of the wiper blade with extensions of the opening extending radially outward from the center of the opening. The connector also includes on the wiper arm a transverse member of a diameter slightly smaller than the diameter of the aligned openings in the blade. A pair of opposed stops extend radially outward from the transverse member with the stops being oriented to align with the extensions on the openings in the blade when the arm and blade are in any position other than the wiping position on the windshield. After the transverse member passes through the openings and the stops pass through the opening closest to the arms, the blade is rotated relative to the arm to secure the arm on the blade ready for wiping the windshield.
