Abstract
An apparatus for enabling a strapless breathing mask to be worn not only in conjunction with a protective helmet but also by itself without the helmet. The mask includes a strapless body, a window shield and a window frame, which can be disconnected from a protective helmet and, by way of the present apparatus, inserted into a resilient holder having a head strap assembly so that the breathing mask can be worn by a user without having to be connected to the protective helmet.
