  • Removable plastic connector
    Patent number: 4195382
    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.
