A locking device for motor vehicle roof trunks has a bottom part and a lid. On two sides of the trunk (1), which extend parallel relative to one another, the lid (3) is pivotable by two hinges around a hinge axis relative to the bottom part (2). The hinges each include a first hinge part (14) associated with the lid (3) and a second hinge part (15) associated with the bottom part (2). All hinges have a common actuating rod (23) which includes hinge pins (30) movable parallel to the direction of the hinge axis (12). Each hinge pin (30) is movably guided in a bearing housing (21) associated with the bottom part (2) and may engage a sleeve (17) associated with the first hinge part (14). A cylinder lock (34) enables all hinges associated with one side to be actuated centrally by actuating the actuating rod 23 towards the closed or open position. By providing the actuating element in the form of an actuating rod (23) and through firm association of the hinge pins, actuation and strength of the locking device are improved.
