The device provides the anchorage of a support element (1a) equipped at its anchorage end (1b) with a spiral clip (3). The spiral clip is able to provoke, in the case of tension on the support element, an anchorage effect on the fixing wall. This end of the support element is able to receive, before the putting in place of the clip, a dowel (4). The dowel has a collar (4a) which presses against the wall. A rear extension passes through the wall and contains independent lips (4b) which form a tunnel for the passage of the support element. When the support element is pulled, the clip presses against the lips of the dowel at force its radial opening by the wedging effect which blocks in position the dowel in relation to the wall. |
