ABSTRACT:
A connector for connecting one type of windshield wiper arm end to a cross pin-type wiper blade. The arm end is releasably attached to the connector which connector has a body portion with a pin-receiving slot on the forward end thereof. The orientation of the pin-receiving slot with respect to the longitudinal axis of the body portion is such that to assemble the arm to the pin on the blade, the axis of the arm and connector relative to the longitudinal axis of the blade approaches 75.degree. to 90.degree.. The pin-receiving slot is forced over the pin on the blade to seat the pin in the slot. Once the pin on the blade is in the slot in the connector, the arm is pivoted relative to the blade until the axis of the arm is substantially parallel to the axis of the blade. The width of the connector is such as to contact the walls of the opening in the blade to guide the arm relative to the blade and at the same time the body portion of the connector fits into said opening in the blade and has a shoulder to prevent the connector from becoming disengaged from the blade during normal use of the blade.
