ABSTRACT:
In a pipe coupling between first and second pipe sections having end areas received within one another, one of the end areas has radial projections which are arranged circumferentially around its outer or inner circumference and extend toward the inner or outer surface of the other end area which has a smooth cylindrical surface adjacent the projections to permit sliding and some tilting of the pipe sections relative to each other.
