A device (H) to be mount to a friable wall (W) comprises a body (10) and at least one main saber tooth (21) extending rearwardly from an upper portion of the body (10) and adapted to be driven into the wall (W) for securing the device (H) thereto. The main saber tooth (12) is arcuate and has a pointed rear free end (22), and is adapted to be arcuately driven into the wall (W). An arcuate and pointy secondary saber tooth (14) extends rearwardly from a lower portion of the body (10) for insertion into the wall (W) before the main saber tooth (12) is inserted therein. The main saber tooth (12) defines a lower enlarged, and typically flat, load-bearing surface (30) for bearing against material of the wall (W). The main saber tooth (12) includes an upper transversally curved surface (32). A hook member (20) is provided on a front part of the body (10) for suspending items therefrom once the device (H) has been mounted to the wall (W).
