Abstract

A fuel injection device for internal combustion engines having a fuel distributor which bears a multiplicity of connecting pieces with radially protruding locking collars and a multiplicity of fuel injection valves constructed as so-called top-feed valves, said fuel injection valves being inserted liquid-tightly into the connecting piece. For the purpose of fixing each of the fuel injection valves in the axial direction as well as for securing the fuel injection valves against rotation in the circumferential direction, in each case a connecting element is provided which engages in an annular groove in the valve housing and engages over the locking collar. In addition, the connecting element has two fixing elements which engage in a positive-locking manner around, in each case, one of the molded elements at least in the circumferential direction, said molded elements being mounted in a defined position on the valve housing and on the connecting piece.
