Improved stopcock for pressure pipes, characterized in that it is formed by a body with an inlet duct and an outlet duct between which a shutter is inserted, which includes a passageway for the fluid and communicates with it, a lateral cavity in which is lodged, shaped in correspondence with it, an elastic-rigid piece whose outer face remains in extension with the surface of the obturator; a spring washer is arranged between it and the elastic-rigid part, which tends to move the latter against the walls of the body of the key so that in the closed position the elastic-rigid part faces the outlet conduit, obtruding it by the action of the spring washer and by the fluid pressure itself.
