Abstract: A crimping unit for radially crimping a crimp barrel along a circumference of the crimp barrel onto a cable includes a plurality of radially displaceable crimping jaws arranged in a circumferential direction, which press the crimp barrel onto the cable in a crimping position. The crimping unit further includes a retaining ring, in which the crimping jaws are accommodated in a radially displaceable manner, and an actuating ring axially displaceable relative to the retaining ring. An axial displacement of the actuating ring in a first direction enables radial displacement of the crimping jaws in the retaining ring into the crimping position. An axial displacement of the actuating ring in a second direction enables an active section of the actuating ring to interact with an active surface of a crimping jaw such that it is movable from the crimping position into a radially spaced position.
