an inner tube which is mounted in an axially shiftable manner in said outer tube, is cylindrical on an inside, and is axially slit multiple times to vary its diameter;
wherein the inner tube tapers conically on an outside toward the support structure front wall at the same cone gradient as the outer tube and, when said inner tube rests against the support structure front wall, said inner tube has completely closed slits and the same inner diameter as an outer diameter of the cartridge outer wall; and
wherein the support structure has an axial pressure device on a second end face that is designed to press the inner tube against the support structure front wall.
