A protective casing is made from a resiliently stretchable material, such as neoprene rubber or the like, and is adapted to retain an article based on the stretchability of the constituent material. In use, a portion of the casing is inverted, or turned inside out, utilizing the resiliency of the material used, so as to permit an article to be inserted into or taken from the casing. To "close" the casing, the previously inverted portion of the casing is stretchingly reinverted, particularly so as to retainingly cover an end portion of the article protruding from the casing.
