Holding device, combination of a holding device and an application component, electric connection device, and actuator system

Holding device for holding at least one cable, comprising the holding device:

• a holder housing, which is formed as hollow body and which comprises a first receiving section and a second receiving section, wherein the first receiving section comprises a cable-receiving opening for receiving at least a section of a cable, which is realized as a through opening of the holder housing and which extends along a first reference axis of the holding device, wherein the first receiving section and the second receiving section are located one behind the other in a second reference axis of the holding device, wherein the second reference axis crosses the first reference axis,
• a connection device with an adapter part which is fixed or fastened to the second receiving section of which is fixed and fastened to the second receiving section and with a coupling piece made of a magnetic material, which is fixed in the adapter part in a positive fitting manner or pressed in the adapter part and which, in a coupling state, couples the holding device to an application component,
• wherein a surface portion of the coupling piece protrudes from the holder housing in direction of the second reference axis and which at least partially forms an outer surface of the holding device, and
• wherein the coupling piece comprises a curved surface portion at least in a section, the orientation of which extends along the second reference axis and which projects away from the cable-receiving opening such that the surface portion of the coupling piece, in the coupling state, is suitable to detachably contact an application component surface portion of an application component and, in the coupling state, to rotatably couple the holder housing relative to the application component at least about the second reference axis.
