ABSTRACT:
The device disclosed by the invention is associated with an element to be mounted in a wall, by insertion in a hole bored in the wall.
It comprises a longitudinal body (4), centring and lateral stabilizing means (7') and longitudinal locking means consisting of a collar (5') and peripheral resiliently retractable portions (10') having a step shaped cut-out (11') so as to form a succession of interrupted circular shoulders so that after insertion the edge of the reception hole in the wall is automatically engaged bweteen the collar (5') and the shoulder whose longitudinal spacing from the collar is the closest, upwardly, of the thickness of the wall.
The device may be integrated in the element to be fixed or consist of a sleeve (1'). With the device, an element may be quickly fixed while working from only one side of the wall.
