ABSTRACT:
Retainers for individual structural components or a plurality of structural components are simultaneously used in order to hold the housing shells of the hearing aid together. To that end, the amplifier structure is secured to a retaining frame that is braced such between the housing shells with screws that the housing shells are drawn together. The screwed connections are arranged such that the screws are not visible when the heariing aid is worn. In an advantageous execution, some of the screws are arranged in the hearing aid and are accessible via the opened battery compartment.
