A closure for multi-point locking of doors or wall parts in housings or cabinets by a—preferably securable—actuating element such as a handle lever comprises a coupling element which is connected with the actuating element mounted in the door or wall so as to be rigid against rotation relative to it and which transforms a rotational movement into a substantially translational movement and which is coupled with a rod that is mounted near the edge of the door or wall so as to be displaceable, one or more locking elements being coupled with the rod by a coupling element, respectively, in such a way that they move from a locked position into an unlocked position (or vice versa) by the displacement of the rod from a first position into a second position, wherein the locking elements and the coupling elements are formed in each instance by a two-armed, one-piece lever, one of whose lever arms is a locking tongue and whose other lever arm is articulated by its end at the rod. According to the invention, the two lever arms enclose an angle of 120 to 150 angular degrees, preferably approximately 135 (or 225) angular degrees, and at least one of the two-armed levers is connected to the driveshaft of an actuating element so as to be rigid against rotation relative to it.
