Abstract: A clip, two or more of which can be employed to retain a canvas stretcher frame within a decorative picture frame. Canvases are typically fixed to a frame formed of a plurality of stretcher bars having rectangular cross-sectional shapes, such frame being adapted for placement into a rabbet groove at the rear of the decorative frame. The disclosed clip has a main body of a length somewhat greater than the width of the stretcher bars. Extending from one end of the main body and integral therewith is a leg having at least one outward projecting point which is adapted to pierce the surface of the decorative frame that defines the rabbet groove. The main body extends across the rear surface of the stretcher bar and has a second leg which resiliently engages the inner edge of the stretcher bar as to retain the clip in place, which in turn retains the stretcher frame within the decorative frame.
