ABSTRACT:
A plug connector for making a connection joint between an axially aligned pair of hollow spacer profiles of insulating glass panes defines a longitudinal axis and a center transverse axis transverse thereto and is configured as an essentially box-type cross section with a center web and a pair of side webs extending from the center web. A plurality of essentially triangular openings are located in the center web on both sides of the center transverse axis, each of the openings defining an apex pointing to the nearest end of the plug connector. The plug connector is further configured as a stamped and bent component made from sheet steel with an essentially U-shaped cross section, with the openings in the center web being configured as wall perforations fully circumscribed by the center web, and with the side webs having a plurality of bent-out elastic retainer catches. Two of the elastic retainer catches are located immediately adjacent to one another on each web side in the region of a profile connection joint and pointing in opposite directions to form a stop for one of the profiles.
