ABSTRACT:
A plug-in connection for the connection of tube and hose lines, in particr for use in tube-line systems of motor vehicles, consists of a male part (S), on which is provided a clip receiving locking groove, a female part (A), into which the male part can be sealingly inserted and on which female-part cavities are provided, with which the locking groove can be axially aligned. The locking of the male part (S) and the female part (A) is obtained by means of a locking clip.
To achieve a long lifetime for the plug-in connection even under changing loads and to achieve a simple handling and inexpensive manufacture, the legs (28, 29) of the locking clip (St.sub.1) can be spread apart by an elastic deformation and can be maintained in the spread-apart position disengaged from the male part locking mechanism. Between the female part (A) and the male part there is arranged a spring (F) which guyes these parts in an axial direction with respect to one another. A seal ring (D.sub.1) is furthermore arranged in a peripheral groove (20) on the male part (S), which seal ring rests sealingly on a cylindrical inner surface (6) of the female part (A).
