An adapter for the articulation of a bar (such as a lock bar of a bar closure) at a lever (such as an actuating lever of the bar closure), including a connection piece with an articulation eyelet at one end and a receiving cavity for the end of the bar at the other end. A clamping device, which extends into the cavity, secures the bar in the cavity. The articulation eyelet has a bore hole for forming a securing device, by which the adapter is fitted to a joint bolt which is carried by the drive lever. The joint bolt has an annular groove and is secured either by a retaining ring in the annular groove or, alternatively, by springing tongues proceeding from an edge of the bore hole, these springing tongues being supported in the annular groove of the joint bolt.
