A grid system for suspension ceilings is disclosed having an end connector providing an inverted, U-shaped end portion adapted to nest over the upper edge of an associated web of a runner extending through the intersection. An integral tongue is bendable through an aperture formed in such associated web to releasably lock the connector to the through runner. The end connector is mounted between opposed, parallel, vertical webs on the associated runner by tabs which extend through web slots. The separate connectors and the runners can be formed of materials having different thicknesses so that the material forming the web and the material forming the connector can be selected to provide the required strength without excessive use of materials. The connectors can be used both in main run cross-run systems, and in basket weave systems.
