A pipe coupling axially connects two pipes having a smooth outer surface. The pipe coupling includes a first split circular ring and a second split circular ring. The first and the second split circular rings are each made from a metal strip. Each of the strips have a radial inner edge surrounding the ends of the pipes. A plurality of teeth are disposed at the radial inner edge of the strips. The teeth are disposed in the plane of the respective rings. A free end of the tooth penetrates into the pipe when the coupling is in the clamped position. The free end of each of the teeth have a circumferential edge that extends transversely with respect to an axis of the pipe coupling. The teeth of the first ring extend at an angle relative to the teeth of the second ring. A side of each tooth facing toward the pipe inserted in the coupling encloses an acute angle with an end surface of the free end of the tooth.
