Abstract: An orthodontic device allows direct attachment to orthodontic wires. A force module central portion is coupled to upper and lower end caps. The end caps have clip members that permit direct clipping onto the orthodontic wires to thereby retain the force module on the orthodontic wires. The clip members comprise first and second spaced apart curved members curving in a first direction and an intermediate curved member curving in the opposite direction. One or more of the curved members may flex to allow passage of the orthodontic wire. Alternatively the curved members have different radii of curvature to form a gap that is slightly smaller than the expected size of the orthodontic wire to permit the orthodontic wire to be forced between the gap and retained within a receiver portion formed by the curved members.
