ABSTRACT:
A connector assembly for use in fastening two plate members together, particularly such members may be mill hole liner ring segments or mill hole liner rings which are fastened together to form a mill hole chute. The connector assembly is comprised of a connector tongue, connector clip and a wedge means. The connector clip is attached to a first plate member and extends outward perpendicularly from said plate member. The connector tongue is attached to a second plate member. In use the two plate members are aligned in edge to edge abutment so that the connector tongue is inserted through the aperture in the connector clip. A wedge means is then inserted through the aperture in the connector tongue. The wedge means is held in place by frictional forces between the wedge, the connector tongue and the connector clip. The wedge means is driven into the aperture causing the plate members to be connected and positioned in edge to edge alignment.
