ABSTRACT:
An improved adaptor is provided for connecting a hook-end wiper arm to a pin-type connector on a wiper blade. The adaptor includes a double-ended pin with one end being removably insertable in a pin-type connector of the wiper blade and with the other end of the pin being gripped by a U-shaped leaf spring or a U-shaped plastic body. The U-shaped spring and U-shaped plastic body have lugs for engaging in an aperture in the end portion of a hook-end wiper arm to removably retain the arm on the adaptor.
