The penetrating longitudinal bore (5a, 5b) of the fastening accommodates a spreading- or expansion-screw. The first section (2) is inserted into an oversized bore in the masonry. The second section (3) and third section (4) are connected to the first section (2). These sections (3, 4) are oversized in relation to the bore. The first section and part of the second section include a longitudinal slot (6) with parallel edges. This permits expansion when the fastening is secured in the masonry. |
