3. A riser section as claimed in claim 2, wherein the two flanges have the shape of a crown concentric to the main tube, of a crown portion or of a rectangular plate.
4. A riser section as claimed in claim 1, wherein the linking means comprise two pins arranged on either side of the at least one auxiliary line element on a circle centred on the axis of a riser.
5. A riser section as claimed in claim 2, wherein the at least one auxiliary line element is connected to the main tube by at least one of the two flanges.
6. A riser section as claimed in claim 1, wherein the connection means of the main tube comprise a bayonet locking system.
7. A riser section as claimed in claim 1, wherein pins of the at least one pin of the linking means comprise a rotating locking element and a synchronization means, and rotation of the synchronization means causes rotation of the locking element.
8. A riser section as claimed in claim 1, wherein the connection means comprise a first rotating locking element, wherein pins of the at least one pin of the linking means comprise a second rotating locking element, and rotation of the first locking element causes rotation of the second locking element.
9. A riser section as claimed in claim 1, wherein the main tube is a steel tube hooped by composite strips.
10. A riser section as claimed in claim 1, wherein the at least one auxiliary line element is a steel tube hooped by composite strips.
11. A riser section as claimed in claim 9, wherein the composite strips comprise glass, carbon or aramid fibers coated with a polymer matrix.
12. A riser section as claimed in claim 1, wherein the at least one auxiliary line element is made of a material selected from the group consisting of a composite material comprising reinforcing fibers coated with a polymer matrix, an aluminium alloy, and a titanium alloy.
13. A riser comprising at least two riser sections as claimed in claim 1, assembled end to end, wherein a first auxiliary line element of a first riser section of the at least two riser sections transmits longitudinal stresses to a second auxiliary line element of a second riser section of the at least two riser sections to which it is assembled by means of a first flange holding an end of the first auxiliary line element around a first main tube of the first riser section and a second flange holding an end of the second auxiliary line element around a second main tube of the second riser section, the first flange and the second flange being secured by pins arranged parallel to the first auxiliary line element and the second auxiliary line element.
14. A riser section as claimed in claim 10, wherein the composite strips comprise glass, carbon or aramid fibers coated with a polymer matrix.
15. A riser section as claimed in claim 1, wherein the teeth of the pins extend along radial directions with respect to axes of the pins.
16. A riser section comprising:
a main tube;
at least one auxiliary line element arranged substantially parallel to the main tube;
a locking system including at least one pin and at least one bore, axes of the at least one pin and the at least one bore being parallel to an axis of the at least one auxiliary line element, the axes of the at least one pin and the at least one bore non-merging with the axis of the at least one auxiliary line element, and
wherein the locking system is configured to engage the at least one pin with other bores of other riser sections, the locking system is configured to engage the at least one bore with other pins of the other riser sections, and the pins are provided with teeth and hollows that cooperate with teeth and hollows of the bores.
17. The riser section as claimed in claim 16, further comprising two flanges connected to opposite ends of the main tube, and the two flanges holding the at least one auxiliary line element.
18. The riser section as claimed in claim 17, wherein the locking system is configured to engage the two flanges with other flanges of the other riser sections.
