Retaining devices for orthodontic brackets comprise means for passing through an opening behind an orthodontic bracket or through an opening between twin-brackets and including means connected thereto for retaining an arch wire in an arch wire receiving slot of a bracket. The retaining means for passing behind an orthodontic bracket includes a bent-over arrangement which springingly wedges in a space defined between the rear of the bracket and, for example, a band to which the bracket is mounted. The retaining device also has an edge which bitingly engages the band, or the like. In the embodiment for a twin-bracket, the retaining means has a rear portion which passes through an opening defined between the brackets of the twin-bracket arrangement for engaging the bracket arrangement with spring-type action. The portion extending in the opening between the brackets may also have a bent-over portion which acts as a spring-type wedge in the space, the bent-over portion having an edge which bitingly engages the band, or the like to which the bracket arrangement is secured. The retaining devices optionally include means for connecting auxiliaries thereto.
