Abstract: The invention concerns a method for setting medium or high power electric cables (2) in the ground, which consists in digging a trench (14) evacuating the materials derived from the trench (14) towards a treatment device, for example by crushing, depositing at least a duct or an assembly of three installation ducts in the trench (14), backfilling the trench (14) with the treated materials and setting in said installation duct (1), at least a medium or high power electric cable (2) by pushing it while injecting water (6a) under pressure into the installation duct (1) so as to use the water (6a) as carrier and discharge fluid for the heat energy resulting from friction between the cable (2) and the installation duct (1).

Abstract: A connection device for making a tight connection between two ends of tubes is provided. The connection device includes a body having two symmetrical and opposite portions for engaging ends of respective tubes, and each of the portions has a hooking element to keep the tube in the connection, and a sealing element for the connection. The hooking element of each portion includes: a truncated chamber arranged in each portion; a longitudinal rib projecting into the truncated chamber; and a split ring whose ends are located on either side of the longitudinal rib. The ring is provided with an internal threading, so as to cause a blocking of the tube by any traction on the tube in a direction opposite to its direction of engagement. The ring is placed free in the truncated chamber, on one hand, and is elastically deformable, on the other.

Abstract: This sealing terminal (2) for an installations duct (1) of tubular shape comprises:

Abstract: A connection device that makes it possible to make a tight connection between two ends of tubes (20), two symmetrical and opposite portions (2a, 2b) for engaging ends of respective tubes (20), with each of the portions (2a, 2b) having hooking means to keep the tube in the connection, and sealing means for such connection, with said hooking means on each portion (2a, 2b) having:
