The second flanges have on their inner diameter a reinforcement ring in or near the plane of the second flange with its outside circumference attached to the second flange. In accordance with the invention the reinforcement ring comprises at its inner circumference a cylindrical stiffener rim with a thickness more or less equal to the thickness of the reinforcement ring
