disclosed is a pressing device for compressingly joining pipe - shaped workpieces , particularly a pipe end and a fitting mounted thereon . at least one of the workpieces is plastically deformed by several press members which are movable along a central longitudinal axis of the workpieces for performing the compression . in order to produce a pressing device with several compression jaws that are comparatively easy to mount and allow the press members to be engaged as centrally as possible during compression , at least two press members are pivotally connected to each other by means of two articulated levers embodied as angle levers for applying compression force . the angle levers pressingly lean on a press member , and both angle levers are train - connected to the same press member .
