Abstract: A device for connection between the ends of tubes (2) protecting one or more cables (9) and a box (4), has a flexible sheath (3) that makes it possible, at the exit from the tubes (2), to connect the cables (9) coming from the tubes (2) to the box in providing for the protection of the said cables (9) and enabling the moving away of the box (4) to be accessed.

Abstract: In a device for placing a structural element in a cable installation conduit in order to sub-divide it, the structural element has a width close to the size of the internal perimeter of the conduit and comprises a plate surmounted by ribs. The device comprises a hot air inlet designed to soften the plate of the structural element; an external cylinder whose diameter is identical to that of the conduit, the cylinder comprising a shaping cone at one end in order to enable the softened structural element in order to gradually take a cylindrical shape; and an internal core fixedly held at a position located in the shaping cone of the external cylinder and positioned inside the softened structural element in order to give it a constant internal diameter when it is being shaped.
