  • the second strain relief component has clamping fixing elements, through which at least part of the electrical cable arrangement can be non-positively fixed to the second strain relief component by clamping. This allows a part of the electrical cable arrangement to be fixed quickly and, in many cases, without tools.

  • the connecting section can be present in addition to the previously mentioned coupling elements.
  • the first strain relief component is present as a separate element from the second strain relief component. Accordingly, the first strain relief component and the second strain relief component can be arranged separately from one another in the housing and can be held independently in the housing.
  • first strain relief component and the second strain relief component can be arranged within the housing.
  • the first strain relief component and the second strain relief component can be actuated independently of one another and in a freely selectable order to relieve strain on the electrical cable arrangement before the housing is closed.
  • the first strain relief component and the second strain relief component can in particular also be designed as components that are separate from the housing and can be inserted into the housing.
  • first strain relief component and the second strain relief component are present separately from one another, can be fixed separately from one another and both are also accommodated within the housing.
