The invention relates to a plug connection (1) for fluid lines comprising two coupling parts (2, 3) that can be fitted together, wherein, in the plugged-in state, said plug connection can be secured in a releasable manner by means of a locking device (4) which consists of two external, radial flange-like holding webs (21, 31) of the two coupling parts (2, 3) axially (X-X) adjacent to each other in the plug direction (S) in the plugged-in state, and a holding part (5) having a circumferentially closed annular contour, which can be mounted in a pre-assembled state on one of the two coupling parts (3) in an axially and radially fixed manner such that it cannot be lost and in the assembled state reaches axially and radially around the holding webs (21, 31) of the two coupling parts (2, 3) with at least one C-shaped radially elastic movable holding portion (53) in the axial section having two collars (51, 52). To ensure that the holding part (5) cannot be lost and for minimisation of the spatial requirement, particularly for disassembly, according to the invention the collars (51, 52) on the holding part (5) are designed with a different size and/or shape such that, in the event of a radially elastic movement outwards from the assembled state of the holding portion (5), a collar (52) which rests against one holding web (21) of the one coupling part (2) in the assembled state releases this holding web (21) of the coupling part (2) while the other collar (51) still engages, at least in regions, behind the holding web (31) of the other coupling part (3) against which it rests. |
