The electrical casing (1) includes a lock element (16) which hinges on an axis within the cover. The lock (16) comprises a finger (36) which, lodges in two windows (28,31) in the cover (3) and the base (2), fastening them together. The electrical casing (1) comprises a base (2) and a cover (3) designed to be fitted over the base. A lock (16) hinges between locking and unlocking positions. The lock (16) comprises a finger (36) which, in the locking position, lodges simultaneously in two windows (28,31) formed respectively in the cover (3) and the base (2). This locks the cover and base together. In the unlocked position, the finger is withdrawn from at least one of these windows. The locking element is pivoted on the cover (3), and the axis of rotation lies perpendicular to the direction in which the cover is moved on to the base. The locking element may also include an elastically deformable blocking element (45) which projects, and determines the permitted movement for the finger. |
