An attachment member (31) includes a tubular metallic shank (2) with an axial through-bore (3) and a slot (8) formed in the jacket of the shank (2) and extending along the entire length of the shank (2), and load application means (14) at the trailing, in the setting direction, end portion (13) of the shank (2). At an opposite, leading end (6) of the shank (2), cutters (7) are provided. The outer diameter of the shank (2) diminishes from the trailing end (4) toward the cutter carrying leading end (6). The shank (2) is anchored in constructional component by reduction of its outer diameter over a substantial portion of its longitudinal extent.
Un élément de fixation (31) comprend une tige (2) métallique tubulaire qui comporte un trou traversant axial (3) et une fente axiale (8) s'étendant sur toute la longueur de l'enveloppe de la tige (2), ainsi qu'un système d'application de la charge (14) disposé sur la partie terminale (13) de la tige (2) tournée vers l'arrière par rapport à la direction d'introduction. L'extrémité avant (6) de la tige (2) présente des arêtes vives (7). Le diamètre externe de l'arbre diminue depuis l'extrémité arrière (4) jusqu'à l'extrémité avant (6) portant les arêtes vives (7). La tige (2), du fait de la diminution de son diamètre, peut être ancrée dans la surface par une grande partie de sa longueur.
