Abstract: This locking ring is adapted to lock a joint between two tubular elements (4, 8). It extends around a central axis (X-X) and comprises segments (50) each having a main part (58) and two circumferential ends (60). Each segment (50) has a shape flaring out from a thin axial side towards a wide axial side. One of the segments (50) comprises a recess (62) for receiving a retaining member (16), which is axially open on the thin side. The receiving recess (62) extends solely through the main part, and it is circumferentially limited on both sides.

Abstract: A device for low voltage electric distribution includes a set of bus bars for feeding a plurality of outlets protected by a circuit breaker apparatuses, characterized in that it comprises a molded insulating structure comprising two vertical parallel walls (1, 2) separated by a horizontal transversal partition (3), with metal rails (10, 20, 30, 40) inserted in the transversal partition and opening onto either side of said partition. One side acts as a support for the bus bars (11, 21, 31, 41) and the other forming power connections (12, 22, 32, 42), with the tips of said power connection being arrange in accordance with the generatrices of a cylinder with a vertical axis situated in the symmetry plane of the structure. The structure, on the side of the supplies is divided by horizontal partitions defining sockets, with each socket capable of receiving an insulating component (66) bearing clamps (71, 72).
