  • To at such Devices to be able to use support tubes that are in scope Have indentations that extend over the entire length of the Extend support tube and therefore simple. make are, according to an advantageous embodiment of the Invention in the field of clamps in the Indentations are used through which the outer contour of the Support tube added to an at least approximate circular shape to ensure a secure and airtight attachment to achieve the clamps.
  • Support tube at its ends the inside diameter of the perforated hose is adjusted.
  • the support tube at its ends expand a diameter that is at least that Corresponds to the inner diameter of the hose, being in this Area there is no indentation.
  • the hose is there then in the area of the attachment close to the support profile, throws so there are no wrinkles in this area either.
  • the hose can So without further ado with the fastening clamp on the support profile be attached. Especially in this case it will also recommended not to close the hose in this area perforate.
  • the hose is mainly in whose longitudinal direction has aligned slots, the are longer than the fastening clamp used is wide, an airtightness of the fastening is most likely to result achieved if the 'hose has no slits in this area having.
  • a device If a device is used, its Support profile not a cylindrical or oval, but one has a rectangular or otherwise angular cross-section, and no filler is to be used in the indentation, it is advantageous to fix the area like this expand that the support profile no longer has an undercut having.
  • the hose can then be attached with a clamp or similar the support profile can be pressed so that a seal on the support profile also in the area of before expanding existing indentation is made possible.
