A plug connector for hollow sections for spacer frames or bar sections of insulating glass panes, the connector having a longitudinal middle web and two parallel side walls joined to the middle web to provide a pair of parallel longitudinal corners, and a plurality of retaining elements intermittently spaced at or immediately adjacent the corners in the middle web; the retaining elements comprising (i) first retaining elements so shape d as to allow entry and retention of a first desired portion of the connector into a first porti on of a hollow section in a first direction but prevent withdrawal of the first desired portion fro m the first portion of the hollow section in the reverse direction to the first direction and (ii) second retaining elements so-shaped as to allow entry and retention of a second desired porti on of the connector into a second portion of a hollow section in the reverse direction but prevent withdrawal of the second desired portion from the second portion of the holl ow section in the first direction. The present invention provides plug connectors that act in the non-critical vertical direction, intermittently at the corners with the solid side walls of the spacer tube, or immediately adjacent thereto in the center web. Deflections of the spacer tu be are, thus, advantageously, only in the vertical direction and of a very small magnitude . Lateral deflections are eliminated, and the multiple window glazings can be efficiently sealed with a minimum of sealant.
