Plug connector

A plug connection comprising

• a hollow profiled element of a spacer frame or of a bar for an insulated glass pane;
• and
• an inserted straight connector, wherein the straight connector comprising:
• a plurality of connector legs originating from a connection point in different directions;
• fin-shaped retaining elements for meshing with the hollow profiled element;
• a base plate;
• a raised support base, wherein the fin-shaped retaining elements are arranged on both sides of the support base with respect to a longitudinal direction of the straight connector in a row one after another at the connector legs on a top side of the base plate and the support base is arranged centrally, with respect to the longitudinal direction of the straight connector and has a center stop for the hollow profiled elements that can be plugged in on both sides at the connection point, the support base having a roof wall and a cavity located under the roof wall, the support base having transverse walls between the roof wall and the base plate, the transverse walls being located at spaced locations in the longitudinal direction and the transverse wall defining a portion of the cavity;
• an axial rib arranged on the base plate between the transverse wall and the adjoining fin-shaped retaining element or retaining elements.

A straight plug connector for hollow profiled elements of spacer frames or bars for insulated glass panes, the straight connector comprising:

• a plurality of connector legs originating from a connection point in different directions;
• fin-shaped retaining elements for meshing with the hollow profiled element;
• a base plate;
• a raised support base, wherein the fin-shaped retaining elements are arranged on a first support base side and a second support base side of the support base in a row one after another at the connector legs on a top side of the base plate and the support base is arranged centrally, with respect to a longitudinal direction of the base plate and the raised support base has a center stop for contacting one of the hollow profiled elements that can be plugged in on one of the first support base side and the second support base side at the connection point, the first support base side being opposite the second support base side with respect to the longitudinal direction, the support base having a roof wall, a first transverse wall and a second transverse wall, the first transverse wall and the second transverse wall being arranged between the roof wall and the base plate, the first transverse wall and the second transverse wall extending in a direction transverse to the longitudinal direction of the base plate, the first transverse wall being located at spaced location from the second transverse wall in the longitudinal direction, the first transverse wall, the second transverse wall, the base plate and the roof wall defining a cavity;
• an axial rib arranged on the base plate between the transverse wall and at least one adjoining fin-shaped retaining element.
