A device for holding bar ends of a stator winding in a dynamoelectric machine that has an inner ring which fits closely against the bar ends and is shaped like the inside of a cone. An outer support has at least one outer ring and a device for clamping the inner ring to the outer support. The clamping device is supported on the end face of the laminated body or on the stator housing. In order to detune the natural frequency of the winding overhang assembly, additional masses are situated between adjacent winding ends, or arranged on the external outer ring and are uniformly distributed over its circumference. The additional masses consist of a multiplicity of mutually insulated metal wires or metal strips which extend in the circumferential direction and are held together by means of an adhesive and a bandage.
