1. A locking device for a motor vehicle bonnet, the locking device comprising:
a locking mechanism with a rotary latch and a pawl for locking the rotary latch in a main latching position;
a striker that is moveable between an intended closed position and an intended open position; and
a catch hook which defines an opening movement and a closure movement of the striker to a secure position which is between the intended closed position and the intended open position,
wherein the catch hook has a barrier which is load dependent and the closure movement of the striker is in a direction of the barrier and limited in a load dependent manner by the barrier when the striker is in the intended closed position, whereby the striker is configured to move to a submerged position beyond the intended closed position in response to an overload force, and
wherein in response to the overload force, the barrier is bent over by the striker so that the striker moves toward the submerged position beyond the intended closed position.
