PCT No. PCT/EP90/00347 Sec. 371 Date Jan. 14, 1991 Sec. 102(e) Date Jan. 14, 1991 PCT Filed Mar. 2, 1990 PCT Pub. No. WO90/10561 PCT Pub. Date Sep. 20, 1990.A windshield cleaning system with a wiper shaft for driving a wiper arm-and-blade assembly is described, which windshield cleaning system comprises an axial bore for forming a washing liquid channel, whereby at least one electric conductor for heating the washing liquid is assigned to the washing liquid channel. Thereby the electric conductor is anchored on a pipe, which is arranged in the bore of the wiper shaft, whereby this pipe extends the end of the wiper shaft by way of at least one end portion and can detachably be connected there with a counter contact piece. Due to the plug connection of the electric conductor an easy assembly is possible.
