The regulator comprises a regulator body with an inlet conduit for connection to a first-stage regulator which supplies a breathable gaseous mixture at a constant pressure and an outlet conduit for connection to a mouthpiece of the user. The group comprises a first bushing defining an intermediate chamber with a bottom wall wherein a central hole is formed, a poppet loosely engaged within the hole, the end of the poppet being connected to lever means, a second bushing engaged in the first bushing and defining an inlet chamber and a third bushing engaged in the second bushing and defining a regulator seat at one of its ends. The head of the poppet engages tightly in the seat and an elastic member is provided coaxial to the poppet in the intermediate chamber for maintaining the head against the regulator seat.
