Locking device for a motor vehicle, comprising: - a rotary latch which is rotatably mounted under spring bias in a housing of the locking device in an opening direction of rotation, and which has a recessed latch contour for receiving in a locking manner a locking bracket to be brought into locking engagement with the locking device when the rotary latch is in a locking position; - a catch hook which is rotatably mounted in the housing under spring bias in a closing direction of rotation opposing the opening direction of rotation, and which has a hook portion for securely engaging behind the locking bracket when the catch hook is in a catch position; - a locking pawl which is rotatably mounted in the housing under spring bias so that, in the locking position of the rotary latch, a locking portion of the locking pawl blocks rotation of the rotary latch in the opening direction of rotation by engaging with a locking contour of the rotary latch, and so that by means of a first unlocking actuation of the locking pawl, directed against the spring bias of said rotary latch, the locking portion of said locking pawl permits rotation of the rotary latch in the opening direction of rotation as far as an unlocking position of the rotary latch which unlocks the locking bracket, a coupling lever which is rotatably connected in an articulated manner to the locking pawl so as to be biased against a cam contour of the rotary latch, said cam contour being provided for controlling a movement of the coupling lever, wherein the cam contour for control is formed such that a coupling end of the coupling lever is released in the locking position of the rotary latch and is in coupling engagement with a coupling portion of the catch hook in the unlocking position of the rotary latch and in the catch position of the catch hook, so that by means of a second unlocking actuation of the locking pawl, directed against the spring bias of the rotary latch, the catch hook can rotate in the opening direction of rotation as far as a release position which releases the locking bracket, and a catch hook lock, which is rotatably mounted in the housing under spring bias, so that a locking portion of the catch hook lock is in engagement with a first locking contour of the catch hook when the catch hook is in the catch position, thereby holding the catch hook in its catch position against the spring bias thereof, wherein the catch hook comprises a second locking contour, so that the locking portion of the catch hook lock is in engagement with the second locking contour of the catch hook when the catch hook is in the release position, thereby holding the catch hook in its release position against the spring bias thereof. - a rotary latch which is rotatably mounted under spring bias in a housing of the locking device in an opening direction of rotation, and which has a recessed latch contour for receiving in a locking manner a locking bracket to be brought into locking engagement with the locking device when the rotary latch is in a locking position; - a catch hook which is rotatably mounted in the housing under spring bias in a closing direction of rotation opposing the opening direction of rotation, and which has a hook portion for securely engaging behind the locking bracket when the catch hook is in a catch position; - a locking pawl which is rotatably mounted in the housing under spring bias so that, in the locking position of the rotary latch, a locking portion of the locking pawl blocks rotation of the rotary latch in the opening direction of rotation by engaging with a locking contour of the rotary latch, and so that by means of a first unlocking actuation of the locking pawl, directed against the spring bias of said rotary latch, the locking portion of said locking pawl permits rotation of the rotary latch in the opening direction of rotation as far as an unlocking position of the rotary latch which unlocks the locking bracket,
