Abstract: A common rail distributor rail (2) for supplying an internal combustion engine with fuel comprises an inner pressure pipe (3), an outer jacket (4) as well as joint pieces (5) for connecting high-pressure conduits. Thereby, the joint pieces (5) are fixedly connected to the outer jacket (4), in particular by way of thermal joining, and by way of this form a double-walled system with a pressure-tight sealing of the jacket.
