Disclosed is a fixing device for fixing an actuation device with push-push kinematics on a component of a motor vehicle. The fixing device includes a housing with a guiding element and a locking recess on its outer surface, an opening in the component for inserting the actuation device, a guiding element on the component, and a locking projection on the component. The guiding elements of the actuation device and the component corporate such that the actuation device is guided into the opening in a predetermined rotational position, and the locking projection and the locking recess lock with each other upon the actuation device being inserted fully into the opening in the predetermined rotational position, and thus fix the actuation device on the component. The locking can be released again by rotating of the actuation device out of the predetermined rotational position.
