A dowel (10) has an anchor pin (20) which is threaded along at least part of its length. An elongated locking element (22) is mounted on the end of the pin to be anchored in the cavity (16), between two elongated parallel brackets (24) connected at their end remote from the locking element by a bridge (26), in such a manner that it can swivel between an insert position flush with the anchor pin and a locking position perpendicular to the anchor pin. The threaded front end of the anchor pin (20) is screwed into a threaded hole (28) in the bridge (26). The locking element (22) is traversed by a threaded hole (38) the median axis of which, in the locking position, is flush with the median longitudinal axis of the anchor pin. |
