An axially holed closing-bit boss extends between the cylinder cores in the profile double cylinder lock, a swivel coupling lever in the hole being activated by the key tip. When the key inserted is removed, the lever is held in a centre position in engagement with coupling recesses in both cores. A leaf spring is fastened in the hole passing through the closing-bit boss (1), fitting against at least one flattened section (16) on the swivel coupling lever (2). This section may be formed on a spacing neck (15) united with the lever, determining the interval of the lever from the hole's internal periphery. |
