An expansion anchor (1) comprising a tubular body (2), which extends along a longitudinal axis (A) and is structured so as to have a head (4) at one end, adapted to be engaged inside a hole obtained in a wall; the head (4) comprising a deformable body (6) made of a first plastic material having a predetermined mechanical rigidity, and at least one longitudinal rigid insert (7), which is firmly integrated in the deformable body (6) and is made of a second plastic material having a higher mechanical rigidity than the mechanical rigidity of the plastic material of the deformable body (6) itself. |
