Abstract: 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.

Abstract: A connecting device for media lines including a coupling element, an insert part and a fastening element. The coupling element has a connection opening and a fluid channel; the insert part can be inserted into the connection opening; and the insert part can be fastened to the coupling element by the fastening element. The fastening element also has at least one control surface. When the insert part is inserted into the connection opening under the action of an installation force, the insert part acts upon the control surface in such a way that the fastening element is moved against a restoring force. If the installation force is sufficient, the insert part slides past the control surface and the fastening element interlockingly locks the insertion part. If the installation force is not sufficient, the fastening element presses the insert part back out of the connection opening.
