a locking mechanism with a catch and a pawl for locking the catch 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, wherein the catch hook further defines a securing position for the striker which is between the intended closed position and the intended open position, wherein the catch hook has a barrier,
