A parking lock control element has an actuator coupled to a parking lock pawl, and a retaining device which works with the actuator to secure the parking lock pawl in the disengaged position. The connecting device is characterized in that the retaining device has a blocking slide connected to the actuator, and a blocking actuator having a slider gap, the width of the slider gap being modified in an actuating manner, wherein the blocking slide can move into the slider gap—when the slider gap is open—releasing the actuator. The connecting device reduces structural complexity and related costs. At the same time, the control element is comparatively robust with respect to manufacturing tolerances, acceleration forces, vibrations, and temperature stress. With minimal auxiliary energy, high holding forces can be achieved to secure the parking lock pawl. An emergency unlocking actuation can also be integrated in a simple manner.
