The hoop-shaped member has a plurality of spaced bendable tangs located around its periphery and extending outward therefrom for piercing the canvas when stretched in place around the frame. The tangs are bendable inward in the rearward direction for securing the canvas tightly around the frame. Also provided in an outer hoop-shaped member adapted to be telescoped around the side edges of the frame and the first hoop shaped member when the canvas has been stretched and secured to the tangs of the first hoop-shaped member.
