Abstract
A behind the ear (BTE) hearing instrument has a coupling between a housing and a sound tube. The sound tube is removably connected to the housing by a coupling connected to the sound tube. A sound-tube-side coupling component has a sound channel leading to the sound tube and a housing-side coupling component has a sound channel leading to a receiver, which, when the coupling is closed, are connected to each other by an acoustic seal. The coupling has a lug and an abutment, which connect the sound-tube-side coupling component to the housing-side coupling component in a form-fit and movable manner, in a spatial direction relative to each other. A locking device is provided that, when it is closed, impedes a movement of the coupling components relative to each other. The lug including the corresponding abutment and the locking device are disposed spatially separated from each other in the coupling.
