A locking device for gates, doors and similar leaves, particularly in plate-enclosed electrical units for heavy current, comprises a housing (6, 6') with handle (3) mounted on the leaf, and an axle (5) having a free end on which is provided a transverse bolt (4) which is arranged to enter into engagement with a retaining element (7) on a frame or post (2). The retaining element (7) has two forwardly-extending webs, each with an aperture (8) arranged for engagement with the bolt (4). The retaining element also comprises a release element (11) arranged to release the energy in a mechanical energy store in the housing when the leaf is moved against the frame, whereby the energy is transferred to the bolt (4) by the turning of the axle (5). |
