Fixing pin, characterized essentially by the fact that it is constituted by a hollow cylindrical body, in one of whose bases a nut is embedded, while from the other base emerge in divergent form, a series of curved legs and with its concave surface directed towards the outside, in such a way that the introduction of said assembly in a previously drilled hole in the surface where it is desired to fix the corresponding object, its subsequent thrust and its coupling with a fixing screw, results in that, due to the divergent character of the aforementioned legs, it is impossible to return to the outside of the pin itself, which, acting in the direction of screwing the aforementioned screw, goes to the rear wall of said surface, pressing with its legs against it.
