Abstract
A plug connection (1) for fluid lines, with two intermateable coupling parts (2, 3), which in an inserted state can be releasably locked via a locking device (4) consisting of two outer radial flange-like retaining ribs (21, 31) of the two coupling parts (2, 3), which are adjacent in an insertion direction (S) and axial (X-X) in inserted state and a retaining part (5) with an annular contour, which in preassembled state can be axially and radially fixed and undetachably assembled on one of the two coupling parts (3) and in an assembled state axially and radially encompasses the retaining ribs (21, 31) of the two coupling parts with at least one radially elastically moving retaining section (53) with a C-shaped axial section having two collars (51, 52). The plug connection incorporates features to ensure the undetachability of the retaining part (5) and minimize the space requirement, in particular during disassembly.
