Abstract

A system, which is used especially as a fuel injection system for the high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element. The holding element has an at least essentially straight first leg and an at least essentially straight second leg. The cup includes at least one recess, which extends through a wall of the cup. The first leg and the second leg are guided through the at least one recess. Furthermore, the connection sleeve of the fuel injector has a collar, which is braced on the first leg of the holding element and on the second leg of the holding element in order to secure the fuel injector on the cup.
