A plug-in connector for hollow sections (24), especially for spacer frames or bar sections of insulating glass panes. The plug-in connector has a middle wall (5) and two side walls (6) joining same with a plurality of lateral retaining elements (12, 13, 14) arranged one after the other in the direction of plugging-in (9) of the hollow sections. At least some of the retaining elements (12, 13, 14) are arranged at the side walls (6) offset transversely to the direction of plugging-in (9) with a said mutual distance (16, 17). The retaining elements may be arranged at various levels to engage at various points on the hollow section.
