Abstract
A press tool for non-detachably connecting through cold deformation a fitting and an end portion of a metal pipe received in a socket of the fitting, includes a wraparound ring for placement over the socket of the fitting, and a machine-operated clamping device. The wraparound ring includes a plurality of hinged links and is open at one closing area between two terminal links which are formed with pockets to form grip points for application of the clamping device. The clamping device has a pair of jaws which terminate in lobed ends for engagement in the pockets of the terminal links. The socket of the fitting has formed interiorly a receiving groove which opens inwardly for receiving at least one holding element which is formed with projections or cutting edges for penetrating the material of the metal pipe during radial cold deformation.
