1. A support member for supporting a shell into the barrel of a breech-loading weapon, the support member comprising a support element with a rim flange, end, and edge casing, and the support member further comprising means for fastening the support element to at least one fin belonging to the tail end of the shell, wherein the means for fastening the support element to the tail end of the shell comprises a retainer part formed onto the edge casing and arranged to circle the inner surface of the edge casing essentially level with the plane of the rim flange, and arranged to reduce the inner diameter of the edge casing by converging toward a longitudinal direction of the shell away from the end of the support element. 2. The support member as claimed in claim 1, wherein the retainer part is arranged at the end of the edge casing. 3. The support member as claimed in claim 1, wherein the retainer part is arranged at a distance from the end of the edge casing. 4. The support member as claimed in claim 1, wherein the thickness of the wall of the edge casing is constant. 5. The support member as claimed in claim 1, wherein the outer diameter of the edge casing is constant along its entire length. 6. The support member as claimed in claim 1, wherein the retainer part comprises a support edge that is fastened by means of a bending element to the edge casing, and the bending of the bending element allows the fired shell to detach from the support member. 7. The support member as claimed in claim 1, wherein the retainer part continuously circles the entire inner surface of the edge casing. 8. The support member as claimed in claim 1, wherein the retainer part is formed of several separate parts. 9. The support member as claimed in claim 1, wherein the retainer part comprises threading grooves in the longitudinal direction of the shell and arranged radially, through the grooves the fins of the shell are inserted to the rear side of the retainer part. 10. The support member as claimed in claim 9, wherein the retainer part comprises a back surface ascending in the longitudinal direction of the shell. 11. The support member as claimed in claim 1, wherein the retainer part is integrated to the edge casing. 12. The support member as claimed in claim 1, further comprising a separate retainer ring arrangeable between the retainer part and the fin of the shell so that a first side of the retainer ring leans against the back surface of the retainer part while a second side is arranged against the fin of the shell so that form-locking is formed between the fin and support member. 13. The support member as claimed in claim 12, wherein the retainer ring is made of a material that burns away in the heat generated by the combustion gases of firing the shell. 14. The support member as claimed in claim 1, wherein at the end of the edge casing, a receiving ring is formed that comprises a surface that converges toward the end of the support element. 15. A method for fastening a support member to a shell, the method comprising arranging to the tail end of the shell a support member that comprises a support element furnished with an rim flange, and fastening the support member to at least one fin in the tail end of the shell, wherein fastening the fin of the shell to the support member by means of a retainer part formed onto the edge casing, the retainer part being arranged to circle the inner surface of the edge casing essentially level with the plane of the rim flange and to reduce the inner diameter of the edge casing by converging toward a longitudinal direction of the shell away from the end of the support element. 16. The support member as claimed in claim 2, wherein the thickness of the wall of the edge casing is constant. 17. The support member as claimed in claim 3, wherein the thickness of the wall of the edge casing is constant. 18. The support member as claimed in claim 2, wherein the outer diameter of the edge casing is constant along its entire length. 19. The support member as claimed in claim 3, wherein the outer diameter of the edge casing is constant along its entire length.
