The dowel has a plastic body (4) with a series of external anchoring projections (6), a tip (22), an outer collar (3), and a lengthwise slot (10) that enables it to be expanded by a screw. The body of the dowel has an oblong cross-section formed by a central parallelepiped and two rounded ends, and it is fitted into a hole of matching shape in a wall so that it can receive a screw in a variety of positions.
