The shank has a screw thread (17) for engaging the second member for retaining the shank therein, and the shank includes a passage (25) extending from an outer head end (3) for reception of a fastening screw (24-26), a toggle bar (5) and at least one frangible connector (20-21-22) attaching the toggle baron the shank in an inoperative position at which the toggle bar extends in the passage of the shank through the second member. The toggle bar includes a ramp surface (27) which is contactable by the fastening screw inserted through operative position at which it extends transversely to the longitudinal axis of the shank rearwardly of the rear surface of the second member. The toggle bar in its operative position includes a through hole (23) which is engageable by the fastening screw, whereby a first member (35) associated with the fastening screw is fixable to the second member (8) upon relative rotation of the fastening screw in the shank to draw the toggle bar into engagement with the rear surface of the second member.
Cette invention concerne une pièce d'ancrage servant à assujettir un premier élément (35) à un second élément (8), une plaque de plâtre ou un matériau de revêtement mural analogue. La pièce d'ancrage est en plastique et comprend une tige allongée (2) destinée à traverser le second élément (8) à partir de la face avant (7) de celui-ci jusqu'à dépasser sa face arrière. La tige comporte un filetage (17) destiné à l'immobiliser dans la masse du second élément, ainsi qu'un évidement (25) partant de son extrémité supérieure (3) et destiné à recevoir une vis de fixation (24-26), une barrette articulée (5) et au moins un connecteur frangible (20-21-22) retenant la barrette articulée sur la tige en position inopérante, soit à l'intérieur de la tige (2). La barrette articulée comporte une surface inclinée (27) sur laquelle prend appui la vis de fixation pour faire basculer ladite barrette en position opérante où elle est transversale à l'axe longitudinal de la tige et en retrait de la face arrière du second élément. En position opérante, la barrette présente à la vis de fixation un trou traversant (23) dans lequel se visse ladite vis pour rapprocher le premier élément (35) du second élément (8) en attirant ladite barrette contre la face arrière de ce dernier.
