A press tool for pressing a receiving part ( 1 ) of an installation element ( 2 ) onto a pipe ( 3 ) inserted into the receiving part has two press elements ( 5 ) which are connected so as to be movable relative to one another. The receiving part ( 1 ) has at least one section ( 4, 21 ) which is formed by the pressing process in such a way that the pressed-on section has an outer shape which is substantially constantly curved in the circumferential direction and is within a specified shape tolerance. Each of the two press elements ( 5 ) has, on the side facing the respective other press element ( 5 ), a pressing region ( 7, 24 ) which is assigned to the section ( 4, 21 ). At least one of the two press elements ( 5 ) is formed to be elastically deformable in such a way that, under the forces acting on the press element ( 5 ) during the pressing process, the shape of its pressing region ( 7, 24 ) changes. The pressing region ( 7, 24 ) which is exposed while the press tool in the rest state is present in the circumferential direction in a shape curved differently from the outer shape. On the other hand, the same pressing region ( 7, 24 ) is present in the circumferential direction in a substantially constantly curved shape corresponding to the outer shape when the pressing region ( 7, 24 ) rests against the section ( 4, 21 ) in the pressed-on state of the closed press tool.
