A clasp for a removable dental appliance includes a stem embedded into and extending from the acrylic portion of the appliance. Two ball clasps extend from the stem and are laterally spaced apart from one another. Each ball clasp has an elongated flexible member and an enlarged exposed end. A bridge segment extends laterally between the flexible members of the first and second ball clasps. The stem and ball clasps can be formed by two substantially parallel wires, with the bridge segment extending generally perpendicularly between the wires near their exposed ends adjacent to the ball clasps.
