The device comprises a shank part 1 which is circular at its front end 1a which is longitudinally slotted at 1b for expansion in a borehole (not shown) in a foundation such as a wall. Rear and 1c is square to resist rotation and formed with opposed ledges 1e engageable into grooves 3b provided by turned- over tabs 3a on two opposite sides of an intermediate part 3, and corresponding grooves 3b on the other two sides of the part 3 receive ledges 2b of a supporting part 2 having a slot 2c and a pin 4 for facing-panel engagement. The groove and ledge arrangement provides for possible adjustment, of the attachment to the panel, in two directions substantially at right angles to one another in a plane substantially parallel to the plane of the panel. <IMAGE> |
