CONNECTING DEVICE BETWEEN A WIPER ARM AND A WIPER BLADE

The invention relates to a connecting device (10; 10a; 10b; 10c) between a wiper arm (12) and a wiper blade (11), wherein the wiper blade (11) has an elongated wiper blade body (13) with an adapter element (15; 15c) which serves for exchangeable connecting to a connection region (25) of the wiper arm (12), wherein the connection region (25) of the wiper arm (12) has a substantially U-shaped mount (30) for the adapter element (15; 15c) with an upper boundary surface (34) and two lateral boundary surfaces (32, 33), wherein the mount (30) overlaps the adapter element (15; 15c) at least in the region of the boundary surfaces (17; 17c, 18, 19), and with a first spoiler element (50; 50b) constructed in the connection region (25) of the wiper arm (12) for increasing the aerodynamic contact pressure of the wiper arm (12) onto the wiper blade (11).
