The crank-shaped tie has one part 2, for inserting in a mounting hole 9 in a concrete wall, having as its end a truncated cone 4. The tie may be rotated in hole 9 so as to adjust the vertical position of the other part 3. A sleeve 6 may be secured by impact, e.g. of tool 4, which causes expansion of sleeve 6 over cone 4. <IMAGE> |
