A connection device for a ventilation element includes a transmission connection and a vent connection, the vent connection connects the connection device to a ventilation element, the component connection has a connection piece extending along a connecting axis, and a torsion ring surrounding the connection piece. A connecting rocker is arranged on the torsion ring, and the torsion ring is connected to the connection piece by a connecting bridge, and the connecting rocker has an actuation section and an engaging section for forming an interlocking connection. The torsion ring runs between the actuation section and the engaging section in a connecting region, in which it is connected to the connecting rocker, and the connecting bridge has a connecting arm, which starts from the connection piece and extends in the direction of the connecting axis up to the torsion ring and retains same at a radial distance from the connection piece.
