A self-locking panel assembly for use as ceiling panels comprising a plurali ty of panel units. Each panel unit is formed out of one or more panel elements and a rail extending across the panel elements. The rail is formed out of a lower section and an upper section that are offset from each other such that at one end of the unit the lower section forms a tongue sticking out, and at the opposite end, the upper section, in combination with the panel element, forms a slot dimension ed to receive the tongue. The ends of the rail are complementary and nonlinear suc h that they fit together. The panel units of this invention are installed in place. The rail of a first panel locks in place with the rail and panel element of the adjacent panel. The edges of the adjacent panels are thus restricted from movement so as to limit the individual free movement of separate panels.</SD OAB>
