1. Spacer tube for the production of a spacer frame for multi-pane insulated glazing having at least two glass panes, having a tube wall, the tube wall having a visible wall, a bottom wall that lies opposite the visible wall, and two side walls that lie opposite one another, for connecting with a glass pane, in each instance, wherein at least one of the two side walls has an embossing that cold-strengthens the respective side wall in order to increase the bending stiffness of the spacer tube,wherein the embossing is configured as a depression, viewed from an inner wall surface or from an outer wall surface of the tube wall, andwherein the embossing does not extend through the entire side wall, so that a wall thickness in embossed wall sections of the side wall is lower than in non-embossed wall sections of the side wall. 2. Spacer tube according to claim 1, wherein the embossing has multiple individual embossed elements that are distributed over the entire side wall, in each instance. 3. Spacer tube according to claim 2, wherein the individual embossed elements are in the form of first X-shaped embossed elements that are disposed spaced apart from one another, and adjacent to one another, viewed in a longitudinal tube direction, respectively, whereby the first X-shaped embossed elements are disposed in one row. 4. Spacer tube according to claim 2, wherein the embossed elements are in the form of second X-shaped embossed elements that are disposed in multiple rows, wherein the rows are spaced one above the other, viewed in the tube height direction, whereby a row) has multiple second X-shaped embossed elements that are disposed spaced apart from one another, and adjacent to one another, viewed in a longitudinal tube direction, respectively. 5. Spacer tube according to claim 2, wherein the second X-shaped embossed elements of the one row are disposed offset, in the longitudinal tube direction, relative to the second X-shaped embossed elements of the row, which is adjacent in the tube height direction to the one row. 6. Spacer tube according to claim 2, wherein a side wall has first and third X-shaped embossed elements that are disposed spaced apart from one another, and adjacent to one another, viewed in the longitudinal tube direction, respectively, whereby the first and third X-shaped embossed elements are disposed alternately, viewed in the longitudinal tube direction. 7. Spacer tube according to claim 6, wherein the third X-shaped embossed elements have two intersecting shanks, in each instance, that have two shank ends, in each instance, whereby the two shanks of the third X-shaped embossed elements are configured to be extended in the direction of the transition wall, in each instance, and extend around the folded edge into the transition wall. 8. Spacer tube according to claim 1, wherein the embossing has a surface-covering pattern that preferably covers the entire side wall, in each instance. 9. Spacer tube according to claim 8, wherein the embossing pattern is a honeycomb pattern embossed into the side wall, in each instance. 10. Spacer tube according to claim 9, wherein the honeycomb pattern has multiple, individual honeycomb cells having a regular, hexagonal layout, which border on one another and are delimited by six crosspieces, in each instance. 11. Spacer tube according to claim 10, wherein the crosspieces are embossed into the side wall, in each instance. 12. Spacer tube according to claim 10, wherein the outer wall surface is even-surfaced in the region of the side walls. 13. Spacer tube according to claim 1, wherein the spacer tube is produced via roll-deformation, from a longitudinal metal strip, and is connected alongside, in the region of two longitudinal edges, particularly welded via a longitudinal weld seam. 14. Spacer tube according to claim 1, wherein the tube wall has a wall thickness of 0.2 to 0.4 mm in the non-embossed wall sections. 15. Spacer tube according to claim 1, wherein the spacer tube has a first transition wall between a first side wall of the at least two side walls and the bottom wall and has a second transition wall between a second side wall of the at least two side walls and the bottom wall, and wherein the first and second transition walls also have an embossing, at least in certain sections. 16. Spacer tube according to claim 1, wherein the embossing extends into the side wall by 10% to 50% of the wall thickness. 17. Spacer tube according to claim 16, wherein the embossing extends into the side wall by 20% to 30% of the wall thickness. 18. Spacer tube according to claim 1, wherein the embossing comprises one or more elongated beads extending in a longitudinal tube direction. 19. Multi-pane insulated glazing, having at least two glass panes disposed spaced apart from one another and adjacent to one another, between which a pane interstice is formed, whereby a spacer frame is disposed between always two glass panes, wherein the spacer frame has at least one spacer tube according to claim 1. 20. Method for production, particularly continuous production, of a spacer tube according to claim 1, having the following method steps: a) Making available a longitudinal metal strip having two lateral longitudinal strip edges and two strip broad sides that lie opposite one another,b) Introducing embossings into the longitudinal metal strip,c) Roll-deforming the longitudinal metal strip into a longitudinally slit endless spacer tube, in which the regions that have the longitudinal edges lie against one another,d) Connecting the two longitudinal edges with one another, particularly producing a longitudinal weld seam via welding the two longitudinal edges to one another,e) In practical manner, calibrating the endless spacer tube to its final cross-section, andf) Cutting the endless spacer tube into spacer tubes having a defined length. 21. Method according to claim 20, wherein the embossings are pressed into the longitudinal metal strip from a first strip broad side, in such a manner that they do not go through all the way to the second strip broad side, so that the second strip broad side remains even-surfaced. 22. Method according to claim 21, wherein the longitudinal metal strip is roll-formed in such a manner that the first strip broad side forms the inner wall surface and the second strip broad side forms the outer wall surface.
