The invention relates to a bracket (1) comprising a base plate (10) on which two retaining wings (11) are formed running parallel to one another and defining an intermediate space (3) in which a wire bow (2) may be held. The intermediate space (3) has a trapezoidal structure such that the wire bow (2) is always pushed upward under the elasticity of the bracket (1) by the inclined retaining wings (22) toward the retaining surfaces (13), such that the wire bow is held in the intermediate space (3) in an aligned fashion without play. The cross sectional shape of the wire bow (2) is selected such that no surface contact occurs in the intermediate space (3).
