摘要

The rail assembly (1) has a supply pipe (2) for feeding or providing of pressurized fuel, where a fastener is arranged in the supply pipe in a partially axial manner. The fastener has an inner contour which is designed such that an internal cross-section of the fastener increases towards an inner space of the supply pipe.
