PCT No. PCT/EP96/02853 Sec. 371 Date May 14, 1998 Sec. 102(e) Date May 14, 1998 PCT Filed Jun. 29, 1996 PCT Pub. No. WO97/09210 PCT Pub. Date Mar. 13, 1997A connection between a wiper arm and the bracket of a wiper blade that is easy to manipulate during wiper blade changes but nevertheless is a secure rotatable connection, for a wiper blade in which a connector is provided on the wiper arm or the wiper rod, is achieved as follows; the connector has a through-hole with inside thread; the through-hole is placed concentrically to a geometric axis running transversely; a screw serving as the hinge pin is screwed into the through-hole, and in this way a releasable frictional engagement between the screw and the connector is created. The screw is fitted on its opposite ends with cylindrical bearing segments which protrude laterally out of the through-hole of the connector and are mounted rotatably in the respective bearing holes in the side walls of he connecting segment of the wiper blade bracket.
