Abstract: A pipe connector clamp 10 for connecting two pipes having smooth ends has a metal jacket 11 comprising a tightening angle 15, 16 at a separation line of the metal jacket 11 disposed along its girth. The tightening angles 15, 16 are supported from below by reinforcement angles 17, 18. A press rivet nut 20 or a press rivet ring 19 hold the tightening angle 15, 16 and the reinforcement angle 17, 18 together by riveting the tightening angle 15, 16 and the reinforcement angle 17, 18 to the press rivet nut 20 or the press rivet ring 19. The riveted mounting of the press rivet nut 20 or the press rivet ring 19 facilitates simplified manufacture of the pipe connector clamp 10.
