  • the pull rope serves to a certain extent in such a way that it clamps the lowermost tube section in the axial direction with respect to the uppermost tube section and thus in other words fixes the other plug connections, which are fixed against one another only in one axial direction, in the other axial direction. So results in a simple and very robust construction, which, for example, also allows to realize the lower pipe sections, which can be connected to each other via these other connectors, with the same pipe diameters.

  • FIG. 1 it can be seen both the pole handle and the pole tip are asymmetrical. These two elements should therefore, so that the stick can be used meaningfully, be defined in their rotational position, concretely, they should be arranged in their rotational position as in FIG. 2a is shown.
  • the tube termination collars 15 and 19 and the corresponding abutment surfaces on the connector 17 are preferably designed so that they are secured against rotation about a form fit. There are various ways to do that in FIG. 3 are shown. For example, as shown in a), it is possible to make the axial abutment surface 20 corrugated on the lower tube end collar 19 (analogous to FIG.
  • Such a determination of the rotational position can be made via the axial stop, but can also be done via the radial contact region of the connector, this is exemplary in FIG. 3b darg Benefici where an intermeshing area is provided with ribs 45 and grooves 46, and the corresponding radial abutment area on the element 21 by corresponding grooves 47 and ribs 48.
  • Such a configuration of a radial abutment portion can either as shown here via a specific engagement portion 44 in addition to the guide pin 49 be formed, but it is also possible to design the guide pin itself with such longitudinally extending ribs and, for example, an inner region of the corresponding lower tube end collar 19 with corresponding inner guide elements.
