1. A line coupling assembly for a motor vehicle, comprising:
a line coupling;
a first line; and
a second line configured to be coupled to the first line via the line coupling,
wherein a coupling-side end of the first line and a coupling-side end of the second line each have a coupling component which are configured such that, when the first line and the second line are completely coupled, the coupling components interact in such a way that the first line and the second line are coupled tightly to each other,
wherein the coupling components are configured such that, when the first line and the second line are not completely coupled, the coupling components interact in such a way that there is a defined inspection gap between an outer wall of the first line and an inner wall of the second line in an area of the line coupling that is larger than when the first line and the second line are completely coupled,
wherein one of the coupling components is an indentation in one of the outer wall of the first line or the inner wall of the second line,
wherein the indentation, starting from a coupling-side end face of the one of the first line or the second line, extends away from the coupling-side end face in an axial direction,
wherein the indentation has a guide section and a fastening section,
wherein, starting from the coupling-side end face of the one of the first line or the second line, the guide section extends away from the coupling-side end face in an axial direction, and the fastening section adjoins the guide section in an axial direction at a distance from the coupling-side end face, and
wherein the fastening section, as viewed in a radial direction, is deeper than the guide section.
