Abstract
A suspension ceiling grid system is disclosed in which cross members are provided with end connectors inserted from opposite sides through openings in runners extending perpendicularly thereto. The end connectors are provided with resilient lock means which interengage when the connectors are inserted into the opening to interlock the runners. Release means provided by a tab formed in the web adjacent to the opening cooperate to define a portion of the opening when in the normal position and are bendable to a release position to enlarge the opening and allow release of the lock means for removal of one or both of the end connectors.
