ABSTRACT:
A clip for securing two T-bar grid beam members in generally perpendicular relation to one another in the formation of a ceiling grid for use, for instance, in a suspended ceiling. A plurality of clip embodiments are disclosed, each comprising a resilient fastener portion adapted for securing the clip to a primary T-bar beam member in generally snap-fastened relation, by forcing such resilient portion down over the head of the beam, and also another resilient fastener portion projecting laterally of the first fastener portion in generally perpendicular relation with respect thereto, and comprising resilient means for connecting a secondary T-bar beam member to the first mentioned beam member and in said perpendicular relationship. The clips may be formed of sheet material, such as sheet metal, and are adapted to be mass produced. The clips can be utilized with both the type of T-bar having a rectilinear head portion, as well as the type having a generally round head portion.
