The system for joining tubular bodies for the transportation of pressurised or depressurised fluids comprises a metal tubular body (1), a plastic connection body (2) in which an end (1a) of said metal tubular body (1) is embedded, the portion of metal tubular body (1) closest to said end (1a) being provided with at least one opening (3) filled with the plastic material of the connection body (2). According to the invention, said opening (3) has one side, proximal to said end (1a) having a first part (4) lying on a plane normal to the axis (X-X) of the metal tubular body (1). The joining system according to the invention achieves optimal distribution of tensions, relative to the area of the tubular body (1) and of the body (2) surrounding the openings (3), produced by the pressure of the fluid that runs in the piping, and therefore ensures that the joint lasts longer and ensures a better seal.
