A compression tool is designed to interconnect pipe ends by plastically deforming metal coupling sleeves thereon. The compression tool has two arcuate jaws which are displaceable between an open position wherein they can be placed upon the tube segments and a closed position, and drive means to displace the jaws in the closing direction. The compression jaws are guided in such a manner that their paths of motion each time subtend an angle that is symmetrical to the center of the compression space of the closed state of the compression tool, this angle opening towards the center. |
