Abstract

A roof rail 10 for a vehicle article carrier, the roof rail consisting of a rail portion 12 and a pair of end supports 14. The end supports 14 or 14′ consist of the same metallic material as the rail portion 12 and are produced from bent tubular metal pieces, which are formed into the end supports 14 or 14′ by an internal high pressure forming process. The forming process does not require prior heating of the bent tubular metal pieces or the forming tool used in the forming process. The end supports (14) each have a neck portion (14a) which includes a connecting peg (16) and a clamping member (18), wherein the clamping member (18) is inserted into a longitudinal groove (20) in the connecting peg (14a) to functionally secure the neck portion to the rail portion (12).
