PCT No. PCT/EP90/00345 Sec. 371 Date Dec. 21, 1990 Sec. 102(e) Date Dec. 21, 1990 PCT Filed Mar. 2, 1990 PCT Pub. No. WO90/10562 PCT Pub. Date Sep. 20, 1990.A windshield cleaning system with a washing system includes a washing liquid pipe non-rotatably fixed in a bore of a wiper shaft, the end of which washing liquid pipe is inserted into a pot-like connecting piece protected against twisting. Thereby the connecting piece is bracelessly centered with respect to the end of the washing liquid pipe so that it can also make a possible wobbling movement of the end in radial direction. Thus a long lifetime of the connecting point between the rotating end of the washing liquid pipe and the non-rotatable connecting piece is achieved.
