ABSTRACT:
A behind-the-ear hearing aid is provided, with an elongated housing and an audio shoe, which is affixed to an end face of the housing in such a way that it can be removed, and a coupling device, with which the audio shoe is coupled to the housing by a sliding movement parallel to the end face of the housing. In addition, affixed to the audio shoe there is a securing device which includes a slider which can be moved crossways relative to the direction in which the audio shoe slides, which in a first position permits the sliding movement of the audio shoe and in a second position prevents the sliding movement. It is thus possible to mount the audio shoe on the hearing aid housing, and to make any necessary contacts, with a double linear movement which is easy to realize.
