Fastener components (68, 99, 148, 305, 340), and method of making fastener components for securing loop-carrying members (112). The fastener component includes a tubular structure (99, 104, 148), and a plurality of discrete projections (72) extending from a surface of the tubular structure. Each projection includes a molded stem of resin integral with the surface from which the projection extends, and a loop~engageable head formed at a distal end of the stem to overhang the surface. In one implementation, a majority of the projections are directed away from a common, open longitudinal end (84) of the tubular structure to allow longitudinal overlap (102) of the fastener component with a complementary loop-carrying member received from the longitudinal end, but to resist subsequent removal of the loop-carrying member toward the longitudinal end due to engagement of the projections.

L'invention concerne des composantes d'attaches (68, 99, 148, 305, 340), et un procédé de fabrication de composantes d'attaches destiné à fixer des éléments à boucle (112). La composante d'attache comprend une structure tubulaire (99, 104, 148), et plusieurs projections discrètes (72) s'étendant à partir d'une surface de la structure tubulaire. Chaque projection comprend une tige de résine moulée faisant partie intégrante de la surface à partir de laquelle la projection s'étend, et une tête à boucle engageable formée au niveau d'une extrémité distale de la tige afin de surplomber la surface. Dans l'un des modes de réalisation, une majorité de projections sont dirigées à une certaine distance d'une extrémité longitudinale ouverte, commune (84) de la structure tubulaire afin de permettre la superposition longitudinale (102) de la composante d'attache avec un élément à boucle complémentaire provenant de l'extrémité longitudinale, mais permettant le retrait subséquent de l'élément à boucle vers l'extrémité longitudinale du fait de l'engagement des projections.
