[0010] This embodiment of the windshield wiper device according to the invention allows for advantageously quick and simple assembly and / or disassembly of the wiper blade, particularly since the connecting unit can be coupled to the movement of the wiper arm or wiper blade. Advantageously, high operating comfort can be achieved, particularly when replacing the wiper blade. In particular, the securing and / or guiding unit allows the connecting unit to be separated from the wiper blade, particularly the fluid connection of the connecting unit to the wiper blade adapter, to be released by rotating the wiper blade along the rotation axis of the wiper arm to release the connection between the wiper blade and the wiper arm adapter.

This design of the windshield wiper device according to the invention advantageously allows for quick and simple assembly and / or disassembly of the wiper blade, in particular because the connecting unit can be coupled to the movement of the wiper arm or wiper blade. Advantageously, unintended damage to the connecting unit, the wiper blade adapter, and / or the fluid channel during disassembly of the wiper blade can be at least substantially avoided.
