A slide plunger device (44) in an expansion device of an expansion tool, the slide plunger (44) and a cooperating expansion head (56) being used to cold-expand an end portion of preferably a plastic pipe (40, 68), so that, immediately thereupon, a connecting nipple, e.g., may be inserted into the plastic pipe (40, 68), the plastic pipe (40, 68) then shrinking firmly round the connecting nipple, so that a pressure-tightening connection is achieved. The device is releasable and has the effect that through an actuator shaft (52) the conical slide plunger (44) may have an actuator releasably arranged thereto, the actuator preferably being of the electromechanical kind and located in a portable gun tool (50). |
