Abstract
A connection is provided for the sections of a separable guide tube and of a drive shaft disposed therein. Shaft sections of the drive shaft are interlockingly coupled together, wherein the ends of the shaft sections interengage one another. One of the shaft sections has an insertion end having a rotationally symmetrical non-circular cross-sectional configuration. A drive sleeve is coaxially secured to the other shaft section and has a coupling cross-sectional configuration that corresponds to the insertion end. Which is introduceable into the driving sleeve. An axial introduction adapter is provided on the driving sleeve and has at least one inwardly projecting introduction ramp, which extends over an angle of curvature between two adjacent large diameters of the coupling cross-sectional configuration of the driving sleeve. The introduction ramp includes an axially decreasing ramp surface that forms a shoulder for the insertion end.
