ABSTRACT:
A windshield wiper blade holder for attachment to a wiper arm of the side mounting type comprises a primary yoke member having a rigid central portion formed with a socket extending transversely through it to receive a side pin on the end of the wiper arm, and formed in and along its under side with a recess having fitted thereinto a resilient latch member which is formed as a unitary molding of a tough polymeric material and is assembled simply by being pressed into the recess until protrusions at one end of the latch member are anchored in a pocket to one side of the socket. A block-like abutment portion of the latch member is held resiliently in a cavity across the socket so that the abutment portion can be displaced downward by an arm side pin thrust into the socket and then will engage in a groove of the side pin to couple the blade holder with the wiper arm. An up-standing finger on the other end of the latch member extends through a passageway to the upper side of the yoke member and can be pressed downward to depress the abutment portion out of the groove of the side pin, thus enabling removal of the blade holder from the wiper arm.
