The present invention relates to an assembly of three bodies interconnected by high-pressure screws and a shaft common to all three bodies and extending from a first body consisting of a hydraulic jack into which oil is injected by an injection pump. The second body causes movement of the shaft, the third body contains an internal plunger with pressure- and hydrocarbon-resistant seals, and a tapered wooden element inserted therein is used to seal the illegal tap. Said body further contains a device made of lead for determining the diameter of the pierced aperture by marking same. The system includes pressure gauges for measuring the pipeline pressure and the machine thrust.
