The at least two clamping main assemblies are longitudinally movable on the frame, so that at least two pipes can be rested in longitudinal alignment with each other. The clamping sub-assembly is disposed at each of the at least two clamping main assemblies, so that the at least two pipes can be retained in longitudinal alignment with each other.
