Forbindelsesindretning og fremgangsmåde til at forbinde et viskerblad med en viskerarm til et køretøjs rudeviskeranlæg

A connecting arrangement for connecting a wiper blade to a wiper arm for a windscreen wiper system of a vehicle. An adaptor for holding the wiper blade is fitted onto the wiper arm in an installation direction running transversely with respect to a wiping surface definable by the wiping movement of the wiper blade. The connecting arrangement includes a securing element designed as a sliding latch arranged on the wiper arm. The sliding latch, which has a U-profile in cross section, serves for the positionally secured holding of the adaptor on the wiper arm, and the sliding latch is displaceable along the wiper arm from an installation position into a functional position securing the adaptor. The sliding latch has a back and two limbs, and at least one projection engaging around the wiper arm on the lower side is arranged on the limbs of the sliding latch.
