Abstract

A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component, in particular a fuel distributor rail. A base body having a receiving space is provided for this purpose. The base body has an opening, via which a fuel fitting of the fuel injector is insertable into the receiving space of the base body. Furthermore, a first annular element is provided in the receiving space, which in the installed state on the one hand interacts with the fuel fitting inserted into the receiving space and on the other hand interacts with the base body. Furthermore, a second annular element is provided in the receiving space of the base body, the first annular element and the second annular element abutting against an outside of the fuel fitting in the installed state.
