A method of forming a retaining device with hooks, wherein: a molding strip is provided that presents an inside face and an outside face, and that has a plurality of cavities, each cavity defining a stem extending from the outside face towards the inside face and including an end forming a head that extends from the stem towards the inside face of the molding strip; the molding strip is positioned on rotary drive means, the inside face of the molding strip being arranged to bear against the rotary drive means; molding material is dispensed against the outside face of the molding strip via material dispenser means arranged facing the molding strip in such a manner as to define a gap between the material dispenser means and the molding strip, the step of dispensing molding material being performed in such a manner as to fill said gap and the cavities with molding material so as to form a tape comprising a base of thickness that is defined by the gap, and first preforms projecting from said base, each comprising a stem and a head, the first preforms being formed by the plastics material in the cavities of the molding strip; and the tape is unmolded in such a manner as to deform the first preforms plastically so as to obtain second preforms of a shape that is different from the first preforms.
