1. Toothed washer, in particular for fixing a tube line introduced in a fluid connector in an insertion direction, comprising:
an annular base having a toothed washer central axis, wherein 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, wherein 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,
wherein 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; and
wherein the annular base has rounded-off torsion reinforcements between each two hinge sections, the peaks of which torsion reinforcements are oriented toward the toothed washer central axis.
