ABSTRACT:
A holder is provided for securing a microphone or earpiece in position inside a helmet. The holder comprises a plurality of tubular rings of soft flexible material. One ring is adapted to be connected to a shell of the helmet, and the other rings are serially connected by resilient, short, thin, soft segments. The rings are dimensioned and arranged so that they can be nested within each other or pulled out to form an extending holder. A microphone or earpiece may be connected to one of the said rings.
