A toothed washer, in particular for fixing a tube line introduced in a fluid connector in an insertion direction, including an annular base having a toothed washer central axis. At the inner circumference of the base, cutting teeth are respectively disposed as a single component on the base radially inward and obliquely to the toothed washer central axis and extending in the insertion direction over an overmolded resilient hinge section and an overmolded retaining section connected thereto. The cutting teeth are configured such that in the event of a fixing movement of the tube line, the cutting teeth cut-in against the insertion direction into an outer circumference of the tube line, wherein the cutting teeth include a cutting surface for cutting into the outer circumference of the tube line to be fixed. The cutting teeth have a support surface, and the support surface is configured set back radially outward as viewed from the cutting surface, so that the cutting-in of the respective cutting tooth is limited during a placing of the support surface onto the outer circumference of the tube line. Furthermore, the invention relates to a fluid connector for tube line installation, in particular fluid-guiding tube lines, including a receptacle section for introducing a tube line in an insertion direction, as well as a retaining element, configured as such a toothed washer, disposed in a receptacle section.

Toothed washer

A connecting device having a connecting body with a receiving opening for a pipeline and a retaining element for securing an inserted pipeline. Inside the connecting body is a release element disposed in an axially displaceable manner such that the pipeline can be released. The release element includes a ring part and snap-in arms separated from each other by longitudinal slots. The outer perimeter the ring part can be sealed by an outer perimeter gasket against an interior perimeter wall of the connecting body, and the interior perimeter of the ring part can be sealed by an interior perimeter gasket against the inserted pipeline. In an assembled state of the connecting device, the outer perimeter gasket can be deformed from its sealing position such that at least one leakage gap is formed in the interior of the connecting device by an interior pressure of a pressurized medium in the pipeline.
