ABSTRACT:
A ceiling system constituted of inverted T support members arranged in a horizontal grid, wherein T members aligned in end-to-end relation are interconnected by a splice member bridging the joint between them and having a pair of horizontally spaced clips respectively projecting through openings in end portions of the webs of the interconnected T members. The splice member is a sheet element having portions bent laterally and downwardly about horizontal bending axes to form the clips, and side edges bent obliquely about vertical bending axes for bearing against the webs of the T members to cooperate with the clips in securely interlocking the splice member and the T members.
