A locking device has adjustable device parts, one of which comprises a locking element and another comprises a support part. A latch can be moved between a closed and an open position. A knee lever comprises a first arm pivotable about a pivot axis and a second arm, pivotable relative to the first arm about a knee joint axis The latch is drivably connected to the knee lever so that in the closed position, the arms are pivoted into a first pivot position located near the dead center point of the knee lever and the knee lever can be positioned against a point of abutment distanced from the pivot axis. The knee lever can be moved by an actuator connectable to an electrical energy storage unit from the first pivot position across its dead center point into a second pivot position corresponding to the open position.
