Locking device for a motor vehicle bonnet

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,
• wherein the closure movement of the striker is limited in a direction of the barrier in response to the overload force by a submersion stop of the catch hook,
• further comprising a guide groove of the catch hook that extends to the barrier and/or to the submersion stop,
• wherein a first lateral wall and/or a second lateral wall of the guide groove are oriented parallel to a movement track of the striker between the secure position and the intended closed position, and
• wherein the guide groove or the first lateral wall of the guide groove provides an indentation to accommodate the barrier when plastically deformed and/or bent over.
