Abstract: A fire extinguisher holder provides for the removable retention of a fire extinguisher therein, for use in the home, office, or other immovable structure where the immobility of the structure precludes any requirement for positive clamping or attachment of the extinguisher in the holder. The present holder comprises a back panel, a base for supporting a fire extinguisher thereon, and an encircling element for precluding lateral movement of the extinguisher until it is lifted clear of the encircling element. The present extinguisher holder is constructed as a single, unitary structure and is devoid of any movable extinguisher retaining elements which would otherwise have to be manipulated in order to remove the extinguisher from the holder. The present holder allows a fire extinguisher held therein to be removed quickly and easily, without any requirement for releasing retaining straps and the like.
