One-piece article obtained by injection moulding, with at least one injection point, said article comprising a main body (20), having a body volume defined by the space within a surface forming an outer envelope, and at least one hook (21), preferably a field of hooks, obtained from the same moulding of the main body of the moulded article, the hook or each hook having a stem of longitudinal axis and a catching part projecting laterally from the stem, characterized in that the volume of the hooks is substantially smaller than the volume of the body, i.e. at least 100 times smaller, preferably at least 1000 times smaller, for example between 100 000 and 100 000 000 times smaller, than the volume of the body, and in that the width, or smallest transverse dimension, of the stems, measured transversely to the longitudinal axis, is smaller than the thickness of the main body, measured along the longitudinal axis of the stems.
