Improvements introduced in the devices for sealing leaks in a hermetic joint between two sections of pipe of a conduit such as a sewer pipe, of the type in which said device, intended to be introduced in the pipe, is provided with an auxiliary body equipped with two end sections closed at their ends and separated by a central section, the peripheral wall of said body or bag being able to take in its end sections a diameter more important than the diameter of the central section, by applying pressure, and auxiliary means which serve to introduce the medium under pressure in the auxiliary body and to ensure the arrival of hardening sealing material beyond the periphery of the central section, characterized in that the auxiliary body, with the exception of the auxiliary device, substantially includes a bag flexible whose wall presents in the diametrical direction and in the two sections it is extreme a length or elasticity or a length and elasticity greater than the length and/or elasticity of the central section.
