ABSTRACT:
A clip formed from a resilient wire rod having a circular cross sectional configuration utilized for installing a canvas stretcher frame within a decorative picture frame. The clip has an elongated central body portion connecting first and second legs at opposite ends thereof. A sharpened projection extends from the free end of a first leg while a resiliently deformable retaining portion is formed adjacent the free end of the second leg. The diameter of the wire rod is smaller than the clearance space formed between the rabbet groove of the picture frame and the adjacent rail or stile of the stretcher frame. The first leg is inserted into the clearance space with the central portion overlaying the clearance space portion of the rearwardly facing edge of the rabbet groove, and thereafter the clip is rotated so the central section swings over the adjacent rail or stile of the stretcher frame. The clip may then be forcibly pushed down so that the second leg grasps the edge of the rail or stile remote from the clearance space. The clip can be used with not only picture frames having shallow rabbet grooves, but also picture frames having deep rabbet grooves wherein the rearwardly facing surface of the rails and stiles of the stretcher frame would be at or below the rearwardly facing surface of the picture frame.
