Abstract

For retention and sound-damping sealing of members introducible into the auditory canal, such as hearing aid housings, otoplastics or ear adapters, an annularly fashioned seal and retainer element can be plugged onto the member and when the member is inserted into the auditory canal, the retainer element fits itself against the walls of the auditory canal and seals the annular gap between the outside contour of the member and the auditory canal in sound-damping fashion.
