  • a generic cable or Schlauchverschraubonnet is known for example from EP1898506B1.
  • That cable or hose fitting comprises a hollow cylindrical nozzle with a longitudinal axis, which is connectable to a housing, and a pressure element in the form of a union nut with a frontal opening for insertion of a cable or a hose.
  • the pressure element is rotatably connected to the neck about the longitudinal axis such that the cable or hose can be fixed on the shell side by tightening the pressure element about the longitudinal axis relative to the neck in the cable or hose fitting.
  • an annular first sealing element is arranged, which is pressed by tightening the pressure member about the longitudinal axis relative to the nozzle from the pressure element shell side to the cable or the hose.
  • a disadvantage of this cable or Schlauchverschraubung is that when installed by less trained personnel not always guaranteed beyond reasonable doubt that the contact pressure of the first seal member is sufficiently high. If the contact pressure of the first sealing element to the lateral surface of the cable or the hose is too low, for example, deposits from the environment can enter the interior of the cable or hose fitting, where undesirable nuclei form and return to the environment through a sealing gap in the first sealing element reach. In particular, when using this cable or Schlauchverschraubung in medical technology and the pharmaceutical and food industry, this fact is particularly disadvantageous, because then the high purity requirements can not be met, quite apart from the health problems that emanate from the deposits can.
  • the object of the invention is therefore to provide a cable or hose fitting, which ensures even more reliable and yet with reasonable effort that the formation of undesirable deposits in the environment facing the environment can be kept as low as possible.
  • the cable or hose fitting according to the invention therefore has the following features:
  • a pressure element having a frontal opening for insertion of a cable or a hose.
  • the pressure element is rotatably connected to the socket about the longitudinal axis in such a way that the cable or hose can be fixed on the shell side by tightening the pressure element about the longitudinal axis relative to the connecting piece in the cable or hose fitting.
  • the pressure element is designed so that it is connected to the neck when tightening the pressure element relative to the nozzle in the direction of the longitudinal axis,
  • the pressure element is further provided on the inside with an internal thread and a conical, directed against the first sealing member, first stop surface,

  • the nozzle can thus be formed entirely without external thread.
  • the clip or locking connection between nozzle and pressure element is preferably covered by the mounted pressure element.
  • the first sealing element has both a sealing function and a holding function to the cable or hose.
  • the friction surface is reduced.

  • the degree of required sealing between the cable or the hose to the first sealing element can be displayed by an optical display element to the fitter. If the sealing effect is sufficient (for example in the unstressed condition of the cable or hose fitting), the installer can see the first sealing element.

  • the degree of required sealing between the cable or the hose to the first sealing element is achieved, for example, that the frontal opening of the pressure element is designed and tuned to the first sealing element that during insertion of the cable or a hose through the frontal opening of the Pressure element, a gap between the cable or the hose and the frontal opening tion of the pressure element is formed.
  • the first sealing element In the untensioned state of the cable or hose fitting, the first sealing element is not visible to a viewer from outside the cable or Schlauchverschraubung ago, because the first sealing element is still completely hidden inside the cable or Schlauchverschraubung.
