A ceiling panel (20) that conceals the grid in a suspended ceiling, having opposed active edges (A, B) with profiles different from one another, and opposed passive edges. Kerfs (33, 35) at different levels in the active edges (A, B), along with a registration step (36) in the one active edge (A), permit the panel (20) to be inserted, or removed, by successive hinge actions. When installed, the panel (20) is locked to the ceiling with no visual indications on how the panel can be removed. <IMAGE> |
