Abstract: A vehicle component for a motor vehicle includes a coupling device including two couplable coupling elements configured to provide, in a coupled state, a fuel-tight connection of two fuel-conducting lines. One of the coupling elements is in a form of a metallic female element which is fixedly connectable to one of the two lines, and an other one of the coupling elements is in a form of a metallic male element which is fixedly connectable to an other one of the two lines. The male element, for coupling purposes, is insertable into the female element, wherein, in the coupled state, an axially extending overlap section with at least one radial seal device is formed between the female element and the male element. A securing device is configured to secure the coupling elements in the coupled state against inadvertent release from one another.

Abstract: A pipe connector for connecting a fuel line of a fuel supply for a motor vehicle engine of a motor vehicle includes an adapter piece that is connectable to the fuel line for insertion into a fuel pipe. A supporting sleeve is inserted into the adapter piece such that the supporting sleeve is configured to make electrical contact between the fuel line and the fuel pipe. The supporting sleeve has, in a subregion, a stop tab which extends out of a lateral surface plane of the supporting sleeve so as to make axial stop contact with the adapter piece.
