The disclosed device for fixing an element to a surface, particularly a thick or thin plaster wall or the like, prefabricated construction or facing panels, comprises at least two separate rigid legs which are parallel to a general direction, and one head (36, 37) which carries said legs. At the vicinity of the head, displacement means such as spacing sectors (34) and an operating screw (35) are provided so that, after driving in, a centrifugal effort can be exerted on the legs which is substantially orthogonal to their direction. Due to the effort developed on the legs, said means enable blocking of the latter in an extremely efficient way in the wall so that a highly strong and resistant attachment is obtained. |
