Abstract

A connecting tube connected at one end to an armature of a fuel injection valve having a valve closing element secured to its other end. The connecting tube is easy to manufacture, it is simple to assemble, it has minimal weight and maximum strength. The connecting tube is resilient elastic and has openings along substantially its entire length and is easy to manufacture by rolling up a sheet-metal blank or by using a rigid spring element with spaced spring coils.
