A crimping tool includes at least three crimping jaws guided for displacement in a tool body. The jaws present first, second and third straight jaw surfaces, wherewith the first jaw surfaces together define a crimping opening. The first jaw surface on each jaw is constantly in slidable abutment with the second jaw surface of an adjacent jaw. The third jaw surfaces abut against and are movable along a respective straight guide surface formed in the tool body. These guide surfaces or extensions thereof define, when projected onto a plane extending at right angles to all guide surfaces, a polygon having the same number of sides as there are jaws present. The first, second and third jaw surfaces of each jaw or their extensions define a triangle, when projected onto said plane. The guide surfaces are so directed that a corner of each jaw, defined by the first and second jaw surfaces thereof, upon movement of the third jaw surface of the jaw along an associated guide surface moves along a plane which extends parallel with the guide surface and falls at right angles to the plane of the polygon and passes through the geometric center of gravity thereof. |
