The invention relates to an adjustable brace (101) comprising a pair of resilient elements (102, 103) which are interconnected at the ends (104, 105). The resilient elements (102, 103) are curved so that one element (102) is predominantly positioned externally in the brace, while the other element (103) is predominantly positioned internally in the brace. Means (11, 16) are provided to cooperate with both elements (102, 103) between their ends (104, 105) to adjust the distance between the elements. If the means (11, 16) are affected in a direction toward each other, e.g. halfway along the brace, tensile forces will be generated in the internal element (103) and compressive forces in the external element (102) and the resulting force will cause the brace (101) to curve additionally. The field of use is preferably for braces which are to extend behind the ear to hold a loudspeaker, side bars of a pair of glasses, etc. which are to be adapted to an individual anatomy.
