Abstract

A fuel injection device for internal combustion engines including a fuel distributor which has a plurality of connection fittings with a radially protruding locking collar. A plurality of fuel injection valves embodied as so-called top-feed valves that are inserted in a liquid-tight manner into the connection fitting. For retention of the fuel injection valves these valves are provided with oppositely disposed catch springs which extend parallel to the valve axis and on faces oriented toward one another have a groove and locking protrusion for engaging the locking collar from behind.
