The special tool for a press for joining connecting elements, arranged in the longitudinal or transverse direction on an incoming carrier belt or in a magazine guide to a front end of an inserted workpiece. The special tools designed as crimping tools comprise at least one pair of grips each, which grips are designed to be axially symmetric, widen in one direction and have an axial bore, and longitudinal slots extending essentially from the widened end face up toward the area of the narrower end face. The axial bore serves to accommodate the workpiece and a plastically deformable sleeve of the connecting elements for this workpiece. The elastically flexible crimping tongues between the longitudinal slots can be compressed in a quasi-hydrostatic manner by an axially symmetric clamping elements. During crimping, first of all the workpiece then the sleeve, or vice versa, can be inserted into the grips. The clamping element guided by the press stroke over the grips slides on their outer surface, which is conveniently designed as a plane cone or in a bell shape and can thus produce the axially symmetric force necessary.
