ABSTRACT:
A compressive tool having two jaw halves that run longitudinally from a rear to a front end and are connected to each other in an articulating manner and that can be moved from an open into a closed position. The jaw halves each have an intake contour at the rear end, and cooperate with a displaceable part of a compressive contour such that the displaceable part of the compressive contour, when being displaced longitudinally toward the front end of the jaw halves, will move along the intake contours and force the latter apart in order to move the jaw halves from the open into the closed position. In order to create a compressive tool of simple design with which also to implement in simple manner compressive connections at large nominal pipe widths, the geometry of the rear ends of the jaw halves is selected such that the two jaw halves are able to overlap in the zone of their rear ends when in the open position in a manner that their angle of aperture shall be independent of the course of the particular intake contour.
