2. The fastening device ( 100 , 200 ) according to claim 1 , wherein the securing element ( 120 ) is configured to form a force fit with the fastening element ( 50 ) through the first rotation ( 124 ) about the first axis of rotation ( 122 ).

3. The fastening device ( 100 , 200 ) according to claim 1 , wherein the first receiving region ( 110 ) is an opening, recess or a through-hole in the main body ( 130 ) of the fastening device ( 100 ).

4. The fastening device ( 100 , 200 ) according to claim 1 , wherein the securing element ( 120 ) has a first portion ( 127 ) and a second portion ( 128 ), wherein the first portion ( 127 ) is configured for engagement with the fastening element ( 50 ), and wherein the second portion ( 128 ) is configured as an actuating device.

5. The fastening device ( 100 , 200 ) according to claim 4 , wherein the first portion ( 127 ) and the second portion ( 128 ) form a substantially L-shaped configuration.

6. The fastening device ( 100 , 200 ) according to claim 1 , wherein the engagement can be released by a second rotation directed counter to the first rotation ( 124 ).

7. The fastening device ( 100 , 200 ) according to claim 1 , wherein the first axis of rotation ( 122 ) is configured to extend substantially perpendicular to a second axis of rotation ( 52 ) of the fastening element ( 50 ).

8. The fastening device ( 100 , 200 ) according to claim 1 , comprising at least one stop element or limit stop element ( 210 ) configured to delimit the first rotation.

9. The fastening device ( 100 , 200 ) according to claim 1 , wherein the fastening device ( 100 ) is configured to be connected to a wiper blade.

10. A windscreen wiper device for a vehicle, comprising:
the fastening device ( 100 ) according to claim 1 ; and
a wiper blade ( 2 ) mounted on the fastening device ( 100 ).

11. The windscreen wiper device according to claim 10 , wherein the wiper blade comprises:
an elongated top part ( 10 ) configured to be at least partially bendable,
an elongated bottom part ( 12 ) configured to be at least partially bendable,
a plurality of connecting elements ( 18 ) for connecting the top part ( 10 ) and the bottom part ( 12 ), wherein the connecting elements ( 18 ) are spaced apart from one another along a longitudinal extent ( 8 ) of the wiper blade ( 2 ) and are fitted to at least one of the top part ( 10 ) and the bottom part ( 12 ) by means of a rotary joint ( 20 ).

12. The windscreen wiper device according to claim 10 , wherein the wiper blade comprises:
an elongated top part ( 10 ) configured to be at least partially bendable,
an elongated bottom part ( 12 ) configured to be at least partially bendable,
a plurality of connecting elements ( 18 ) for connecting the top part ( 10 ) and the bottom part ( 12 ), wherein the connecting elements ( 18 ) are spaced apart from one another along a longitudinal extent ( 8 ) of the wiper blade ( 2 ) and are fitted to at least one of the top part ( 10 ) and the bottom part ( 12 ) by means of a rotary joint ( 20 ), wherein the connecting elements ( 18 ) are configured to allow for a movement of the top part ( 10 ) and of the bottom part ( 12 ) in relation to one another with a movement component along the longitudinal extent ( 8 ) of the wiper blade ( 2 ).

13. The fastening device ( 100 , 200 ) according to claim 1 , wherein the securing element ( 120 ) is configured to form a form fit with the fastening element ( 50 ) through the first rotation ( 124 ) about the first axis of rotation ( 122 ).

14. The fastening device ( 100 , 200 ) according to claim 13 , wherein the securing element ( 120 ) is configured to also form a force fit with the fastening element ( 50 ) through the first rotation ( 124 ) about the first axis of rotation ( 122 ).

15. The fastening device ( 100 , 200 ) according to claim 1 , wherein the fastening device ( 100 ) is configured be connected releasably to a wiper blade.

16. The windscreen wiper device according to claim 1 , wherein the second receiving region ( 150 ) includes an undercut ( 152 ).
