A flame retardant fastener (10) adapted for releasable engagement to a second fastener. A backing layer (22) of the fastener is constructed of a flame retardant polymeric material having an exposed bonding surface and a support surface. A multiplicity of flexible, resilient stem portions (26) extend generally perpendicular to the bonding surface. The distal stem portions have an enlarged head portion (30) located on a distal end of the stem portion. The enlarged head portions (30) have a top surface opposite the distal stem portions and a latching surface (40) opposite the bonding surface. The head portions (30) are disposed to afford movement along different portions of the backing layer and into releasable engagement with a second fastener. A non- flame retardant, pressure sensitive adhesive (33) is applied to the support surface.

Cette fixation ignifuge (10), conçue pour se crocher de façon amovible dans une autre fixation, présente une couche support (22) réalisée dans un matériau polymère ignifuge présentant une surface de liaison exposée et une surface de support. Une multiplicité d'éléments en forme de tiges (26) souples et élastiques, s'étend généralement perpendiculairement à la surface de liaison. Les portions distales de ces tiges (26) présentent sur leur extrémité une tête élargie (30), laquelle comporte une surface supérieure opposée à la portion distale des tiges, et une surface d'enclenchement (40) opposée à la surface de liaison. Les têtes (30) sont espacées de manière à ce que l'on puisse mouvoir différentes portions de la couche d'appui, et crocher ces têtes, de façon amovible, dans une seconde fixation. On a appliqué, sur la surface de support, un adhésif (33) ignifuge et autocollant.
