<p>The invention concerns a device for setting up additional networks by means of an installation equipment (12) using a pressurised fluid for displacing in the duct the additional cable or tube, said installation equipment comprising a cylindrical sleeve (13) capable of being urged around said duct (5) end and to be sealingly connected thereto. The invention is characterised in that it comprises an extender (14) adapted to be inserted between the duct (5) end and the sleeve (13) of the equipment (12), said extender consisting of two semi-cylindrical shells (14a, 14b) capable of being assembled along a diametrical mounting surface (15) to form a tubular body defining a longitudinal passage (16) and whereof one of the ends consists of a smooth cylindrical bearing surface (19), with the same external diameter as the duct (5), and capable of being sealingly engaged in the sleeve (13) of the equipment (12), and of being sealingly screwed into the duct (5) end.</p> |
