Abstract: A mounting system incorporates a supporting panel (1) and a mount (4). The supporting panel incorporates cavities (2, 3) having an aperture (10) in a front face of the panel. The cavity widens from the aperture to a hook receiving portion (11) having upper and lower surfaces, with at least the upper surface incorporating a recess (39) and the lower surface incorporating an inclined bearing surface (38). In use the hook is arranged to be located in the hook receiving portion (11), with a distal portion (15B) of the hook being located within the aperture and rotated so that the hook passes the aperture and locates within the hook receiving portion. Further, to resist withdrawal of the hook from the cavity, the distal and proximal portions are arranged to abut respective ones of the upper and lower surfaces and to become wedged between those surfaces.
