Trunking connecting device

A device for connecting at least two lengths of a trunking adapted to bear against a support surface, said device including a plate for joining backs of trunking base sections, said backs of said trunking base sections having substantially plane rear faces adapted to bear against the support surface and opposed top faces, said plate having a rear face adapted to be flush with said rear faces of said backs and said plate having on each of its edges adjacent transverse edges of said trunking base sections rear and top longitudinal tongues respectively adapted to bear elastically on the rear face and the opposite top face of the corresponding back, said rear tongues being substantially flat and having a thickness from about 0.2 mm to about 1 mm, wherein said plate has at least two said transverse edges adapted to be placed adjacent respective transverse edges of two trunking base sections.

A device for connecting at least two trunking base sections, including a plate for joining backs of said trunking base sections, said plate having on each of its transverse edges adjacent transverse edges of the respective trunking base sections longitudinal tongues adapted to bear on two opposite faces of each of said backs, which tongues are substantially flat, have a thickness from about 0.2 mm to about 1 mm, and are adapted to bear elastically against said opposite faces of said back,

• wherein said plate has at least two transverse edges adapted to be placed adjacent two transverse edges of respective trunking base sections, and
• wherein said plate carries on its top face a pillar with an orifice opening onto a rear face of said plate, said orifice forming a passage for a fixing member for fixing said plate to a support.
