Coupling for tubes, which is essentially characterized by being formed by a groove located at the end of the tube and intended to accommodate an elastic ring that is placed inside a spherical void made in a choke ring divided into two parts, whose ring receives the push in the coupling phase and allows the play of the neck of the device when proceeding to the flexing of the ends of the tubes.
