The invention relates to a press (1) with gripper rails (3) for grasping and relocating workpieces onto a work table (5), the gripper rails (3) being movable in a horizontal plane and vertically by a transfer device (2). The gripper rails (3) are connected to the respective parts (50, 51) of the transfer device (2) by means of gripper rail couplings (14), a locking mechanism (17) with a tie rod (18) being provided, which locks or frees the gripper rail coupling (14). To actuate the locking mechanism (17), an actuating element (19) is provided which displaces the tie rod (18) between a holding position and a releasing position and which can be actuated by the gripper rail coupling (14) being lowered or raised. Furthermore, the locking mechanism (17) has a spring element (34) which holds the tie rod (18) in the holding position. Finally, the locking mechanism (17) has a latching mechanism (38) with a detent (39), which fixes the tie rod (18) in the releasing position and which is freed automatically when the gripper rail coupling (14) is being coupled.
