Abstract
A framing bar connector for firmly connecting adjacent framing bars of a frame through a simple action without requiring any special tool. The framing bar connector is formed in the shape of a bifurcate lever having a pair of legs each provided at the respective free ends thereof with eccentric cams, respectively. In assembling a frame, the eccentric cams are inserted in dovetail grooves formed in the backsides of the adjacent framing bars, respectively, and then the bifurcate lever is fully turned down, so that the eccentric cams engage firmly with the respective bottom surfaces of the dovetail grooves and the inner surfaces of flanges defining the dovetail grooves, respectively, to connect the adjacent framing bars firmly.
