The invention relates to a cuff for orthotic treatment of joint or muscle pains in the region of joints of the human or animal body, which as a cross cuff has a first cuff part (1) for application on a first body part below the joint and a second cuff part (2) for application on a second body part above the joint, wherein the two cuff parts are joined to one another by means of a connection region (3) and in each case are formed from a belt that is provided with fastening means and may be laid around the respective body part, wherein the connection region (3) between the two cuff parts on placement of the cuff on the body in the region of the inside of the joint impedes extension of the first body part with respect to the second body part, in that the connecting region is displaced under tensile stress. According to the invention, at least one partial region (4) of the second cuff part (2) above the joint is made to be stretchable (FIG. 1).
