The invention relates to a composite part, especially a cross member between the A columns of a motor vehicle. Said composite part comprises an open metal profile (2) and a channel (3) disposed therein, at least partially constituted of a plastic material and extending along the metal profile (2). An insert part (4, 22) produced from a plastic material is fastened on the wall of the metal profile (2) in such a manner that a retaining contour (10) configured on an opening (11) in the wall of the metal profile (2) and shaped from said profile undercuts the plastic material of the insert part (4, 22) pressed into the contour, thereby providing the channel (3) with a wall and/or mechanically stabilizing it.

The invention claimed is: 1. A composite part, especially a crossmember between A-pillars of a motor vehicle, having an open metal section and a duct which is arranged therein, is formed at least partially from plastic and extends along the metal section, wherein, in order to form a wall and/or mechanically stabilize the duct, an insertion part which is fabricated at least partially from plastic is attached to the wall of the metal section in such a way that a securing contour which is shaped from said metal section, on an opening in the wall of the metal section, undercuts the plastic of the insertion part which is pressed therein. 2. The composite part as claimed in claim 1, wherein the securing contour is embodied as a punched-collar-like elevated portion of the metal section. 3. The composite part as claimed in claim 1, wherein the metal section is embodied as a hat section. 4. The composite part as claimed in claim 1, wherein a further plastic part for forming at least part of the wall of the duct. 5. The composite part as claimed in claim 1, wherein the insertion part has a reinforcing rib structure. 6. The composite part as claimed in claim 1, wherein the duct only partially fills the metal section. 7. The composite part as claimed in claim 6, wherein a plurality of ducts are arranged inside the metal section. 8. The composite part as claimed in claim 6, wherein a cable duct is arranged inside the metal section. 9. The composite part as claimed in claim 2, wherein the metal section is embodied as a hat section. 10. The composite part as claimed in claim 2, wherein a further plastic part for forming at least part of the wall of the duct. 11. The composite part as claimed in claim 3, wherein a further plastic part for forming at least part of the wall of the duct. 12. The composite part as claimed in claim 2, wherein the insertion part has a reinforcing rib structure. 13. The composite part as claimed in claim 3, wherein the insertion part has a reinforcing rib structure. 14. The composite part as claimed in claim 4, wherein the insertion part has a reinforcing rib structure. 15. The composite part as claimed in claim 2, wherein the duct only partially fills the metal section. 16. The composite part as claimed in claim 3, wherein the duct only partially fills the metal section. 17. The composite part as claimed in claim 4, wherein the duct only partially fills the metal section. 18. The composite part as claimed in claim 5, wherein the duct only partially fills the metal section. 19. The composite part as claimed in claim 7, wherein a cable duct is arranged inside the metal section.
