ABSTRACT OF THE DISCLOSURE: A frame for stretching artists' canvases comprises hollow sections in the recesses of which are inserted an insert that forms an angle at the corners. Each insert has a notch in which the bent end of a square spring fits. The spring is solid at the other end with a block that can slide in a guide and is provided with a tension screw. By the screw being tightened, the hollow sections are thrust outward, leaving a space between them, and causing the stretching of the canvas.
