Windscreen wiper device

A windshield wiper device (100) for a vehicle, with a fastening element (52), comprising

• an installation element (40), which is configured to be mounted on the fastening element (52), wherein the installation element (40) includes a hollow cylindrical-shaped body that includes a securing element (41) in the form of a spiral-shaped cut-out along the hollow body, the spiral-shaped cut-out being open toward a top side of the installation element (40), and
• a wiper blade (2) with
• an elongate upper part (10), which is configured to be at least partially bendable,
• an elongate lower part (12), which is configured to be at least partially bendable,
• a plurality of connecting elements (18) connecting the upper part (10) and the lower part (12), wherein the connecting elements (18) are spaced apart from one another along a longitudinal extent (8) of the wiper blade (2), and wherein the connecting elements (18) are configured in order to permit a movement of the upper part (10) and of the lower part relative to each other with a movement component along the longitudinal extent (8) of the wiper blade (2),
• a wiper-blade-side fastening part (20), wherein the wiper-blade-side fastening part (20) is configured such that, by means of a rotation of the wiper-blade-side fastening part (20) relative to the installation element (40) a portion of the wiper blade-side fastening part (20) extends into and rotates relative to the installation element (40), and an engagement can be formed in order to connect the wiper-blade-side fastening part (20) to the installation element (40), wherein the entire wiper blade is configured to rotate to form the engagement and connect the wiper blade-side fastening part (20) to the installation element (40), wherein the installation element (40) includes a hollow cylindrical-shaped body that includes a securing element (41) in the form of a spiral-shaped cut-out along the hollow body, the spiral-shaped cut-out being open toward a top side of the installation element (40).
