ABSTRACT:
The connecting link is manufactured from an elongated hollow extrusion of aluminum, which can be cut to any desired length and bent, as required. Molded plastic coupling members have tongues which are inserted into the open ends of the hollow extrusion and crimped in place to hold them securely. The coupling members have integrally formed socket structures to receive complementary ball structures which form the pivot connections of the wiper system.
