Abstract

The invention relates to a fuel injector (10) for injecting fuel into the combustion chamber of an internal combustion engine, having a holding body (14) and at least one nozzle body (22), wherein the nozzle body (22) is fastened to the holding body (14) of the fuel injector (10) under preload by means of a nozzle clamping element (16), characterized in that the nozzle clamping element (16) is connected to the holding body (14) by means of a latching connection (46, 56).
