Abstract
A locking connection used to join the cross runners and main runners of a suspended grid ceiling system. The main runners are provided with periodic openings through which the cross runner ends are inserted and thereby locked together. Each cross tee end connector contains a resilient finger which engages the main runner upon insertion. Further, each connector has apertures and raised detents which will mate with those of a like opposing cross tee end connector when both are inserted through the same main runner opening. A locked grid intersection can be disengaged by depressing the resilient finger holding the main runner, rotating the main runner over the cross runner end connector, and pushing the cross tee end vertically free.
