Abstract

A fuel injection device for internal combustion engines has a fuel distributor device with at least one pipe connector in whose receptacle an injection valve is inserted by its inflow-side, upstream end. A connecting element serves for fixing the injection valve in position axially on the pipe connector of the fuel distributor device and also for fixing it in the circumferential direction. The connecting element, which is constructed as a plastic clip, includes a disc-shaped, circular ring-shaped base element with an inner opening through which the inflow-side end of the injection valve runs in the installed state, the disc-shaped base body being positioned in a circumferential groove of the injection valve. The base element includes two legs which can be closed or opened by means of a locking connection. Locking elements extend perpendicularly to the plane of the base element and ensure that the injection valve is fixed in position axially on the pipe connector, and fixed in the circumferential direction, by virtue of a fixing lug which engages around and behind, respectively.
