Device for facilitating the connection of contiguous prefabricated electric conduits

The invention concerns a tool to facilitate the connection of rectilinear and/or angular contiguous conductor elements, in the formation of prefabricated electric conduits, each one having a framework or profile and busbars positioned in said profile and made to fit into those of another element by means of a connecting device. The tool comprises a manoeuvre lever (11) and two pull rods (12) connected to said lever, facing from opposite sides and each having end means (16, 17) to engage, in different positions and conditions, with the holes or openings (23) provided at least in two opposite sides of the profile of the conductor elements to be drawn together in response to an angular movement of said lever. The end means are provided to engage with the elements to be joined on one of their sides or crossways on two opposite sides.
