Abstract

The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle (20) is connected to the rotor (30) so as to transmit a torque and is held on the rotor (30) by a clamping spring (50). The clamping spring (50) has a receiving area for a magnet (60). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle (20) and the rotor (30) is triggered by an external influence on the magnet (60) (FIG. 1).
