ABSTRACT:
The pressing tool (10) comprises two holding members (26,28) adapted to be moved towards each other and having press dies (44,46) displaceably arranged thereon. Adjacent press dies (44,46) are oriented at a right angle to each other, with two press dies (44) being supported on one holding member (26) and two further press dies (46) being supported on the other holding member (28). The press dies (44,46) of both holding members (26,28) can be displaced along an axis extending at an angle of about 45.degree. to the moving direction of at least one of the two holding members (26,28). Prior to the pressing process, the press dies (44,46) are spaced from each other, and during the pressing process, while the holding members (26,28) approach each other, the press dies (44,46) move towards each other until reaching their final closing position. Due to the displaceability of the press dies (44,46) on the holding members (26,28) and the fact that all of the press dies (44,46) are displaced by a rotational angle of about 45.degree. with respect to the moving direction of the at least one holding member (28), the press dies (44,46) are centrically guided during the pressing process so that they move radially towards the pressing member (49) to be connected by pressing action.
