Claim:
1. A connector for fluid lines comprising a coupling part and a counter-coupling part that can be plugged together in a plug-in axis (X), a locking device that releasably locks the coupling part in a position in which it is plugged together with the counter-coupling part, the locking device including a radially elastically deformable holding element held outside on the coupling part and at least partially encompassing the coupling part circumferentially, wherein the holding element radially and axially positively encompasses two outer, radial, holding bars of the coupling part and of the counter-coupling part with at least one holding section having an axial C-shaped section when in the coupling position, the holding element, when positioned on the coupling part, being engaged with the coupling part by way of a fixation structure such that the holding element can be oriented in different relative rotational positions and be fixated in each of the rotational positions to prevent a free, unrestricted rotation of the holding element relative to the coupling part about the plug-in axis (X), the holding element being fixated in the different rotational positions against free, unrestricted rotation by positive force and stepped latching engagement of the fixation structure, the fixation structure including a circumferential latching contour of the coupling part and at least one latching cam of the holding element, the circumferential latching contour defining steps about the coupling part and corresponding to the different rotational positions, the latching cam engaging with the latching contour at the steps in the positive force and stepped latching engagement.
