ABSTRACT:
An improved wiper arm and connector head arrangement which may be readily assembled without use of special equipment by means of inserting opposed bosses on the head into corresponding open-sided recesses on the arm and then relatively rotating the head and the arm, to a position locating a tongue member on the head into a groove in the arm whereby the bosses can no longer be extracted through the open side of the recesses and therefore the head is attached to the arm.
