An expanding insert, for anchoring articles to solid walls, comprising an outer sleeve (1) to be inserted into a hole (9) formed in a wall and provided with an expanding portion (10) and an outer flange (2), in said sleeve (1) there being slidingly housed a shank (4) provided, at said expanding portion, with a countersunk and enlarged head (5), and projecting from said outer flange for a length to be engaged by a riveting machine, said shank being provided, at a region inside said sleeve, with a weakened portion (6), said expanding portion of said outer sleeve being defined by the enlarged portion (11) of a hole formed in said sleeve and leading to a narrowed portion (12) of said sleeve effective to operate as an abutment member for said shank for breaking said shank at said weakened portion, characterized in that the diameter of said head (5) and that of said enlarged portion (11) as well as the location of said abutment member in said sleeve are selected in such a way that, as a pulling force is applied on said shank by said riveting machine, said head (5) will enter said enlarged portion (11) thereby expanding it radially against the inner surface of said hole (9) for a substantial part of the length of said portion, whereby in the radially expanded condition of said sleeve said head is completely enclosed by said sleeve.
