This allows for a particularly advantageous separation of the electrical and fluid components of the wiper adapter. It also enables advantageous simplicity in assembling the windshield wiper assembly.

[0019] Furthermore, it is proposed that the at least one electrical line for supplying power to the at least one wiper blade is connected to the at least one cover element via a locking connection and / or adhesive connection.
