A box for electrical components adapted to be fixed suspended to a busbar conduit, comprising: - a container comprising a base and a plurality of side walls (22a, 22b, 22c, 22d), which extend from the base to an edge that is spaced from the base in a longitudinal direction (Y-Y), - two jaws, that are rotatably attached to one of the side walls (22a, 22b, 22c, 22d), each jaw having an attachment member configured to attach the jaw to a busbar conduit, - two pivots, the two jaws being rotatable about respective pivots between a closed orientation, in which the attachment members are spaced apart at a first distance, and an open orientation, in which the attachment members are spaced apart at a second distance, which is greater than the first distance, - two guides, each extending between a first end and a second end which are spaced apart in the longitudinal direction (Y-Y), each pivot being slidable along a respective guide, - locking members configured to lock the jaws relative to the container in the closed orientation, both when the pivots are located at the first ends of the guides and when the pivots are located at the second ends of the guides, characterized in that each guide, at the first end, is oriented in a first sliding direction, and - either the first slide direction is orthogonal to the longitudinal direction (Y-Y), - or the first sliding direction has a longitudinal component directed away from the second end, each guide thereby preventing the respective pivot, when the pivot is located at the first end and the locking members lock the jaws in the closed orientation, from moving in directions having longitudinal components (Y-Y) oriented toward the second end, wherein the guides are shaped such that, when the container is held suspended by the jaws and the pivots are located at the ends (41, 42) of the guides with the jaws being locked in the closed orientation by the locking members, the weight of the container maintains the pivots at said ends (41, 42). - a container comprising a base and a plurality of side walls (22a, 22b, 22c, 22d), which extend from the base to an edge that is spaced from the base in a longitudinal direction (Y-Y), - two jaws, that are rotatably attached to one of the side walls (22a, 22b, 22c, 22d), each jaw having an attachment member configured to attach the jaw to a busbar conduit, - two pivots, the two jaws being rotatable about respective pivots between a closed orientation, in which the attachment members are spaced apart at a first distance, and an open orientation, in which the attachment members are spaced apart at a second distance, which is greater than the first distance, - two guides, each extending between a first end and a second end which are spaced apart in the longitudinal direction (Y-Y), each pivot being slidable along a respective guide, - locking members configured to lock the jaws relative to the container in the closed orientation, both when the pivots are located at the first ends of the guides and when the pivots are located at the second ends of the guides, characterized in that each guide, at the first end, is oriented in a first sliding direction, and - either the first slide direction is orthogonal to the longitudinal direction (Y-Y), - or the first sliding direction has a longitudinal component directed away from the second end, each guide thereby preventing the respective pivot, when the pivot is located at the first end and the locking members lock the jaws in the closed orientation, from moving in directions having longitudinal components (Y-Y) oriented toward the second end, wherein the guides are shaped such that, when the container is held suspended by the jaws and the pivots are located at the ends (41, 42) of the guides with the jaws being locked in the closed orientation by the locking members, the weight of the container maintains the pivots at said ends (41, 42).
