Abstract: A method wherein a first unit (10) is provided having a field of grip elements (12), and a second unit (20) provided with retention elements (22) suitable for co-operating with the grip elements (12) of the first unit (10) in order to provide a self-gripping fastening. The first and second units are put into contact in such a manner that the grip elements (12) of the first unit and the retention elements (22) of the second unit provide a self-gripping fastening (F). A treatment zone of the self-gripping fastening is treated in order to deform the grip elements (12) of the first unit (10) and/or the retention elements (22) of the second unit (20), whereby the first and second units (10, 20) are permanently secured to each other, thereby forming an assembled structure.

Abstract: A hooked retaining device (100) for defining at least a portion of a reception groove formed at the periphery of an article comprises a retaining element (10) made by injection molding. The retaining element has a first side wall (11) and a second side wall (12) that are spaced apart from each other in a lateral direction, and a base (20) connecting together said side walls (11, 12). The side walls (11, 12) and the base (20) define a retaining groove (14) that is open in a main direction (z) in order to receive a counterpart having hooks or loops. According to the invention, at least one of the side walls (11, 12) presents a plurality of hooks (30) adapted to co-operate with the counterpart, each hook (30) having at least one hooking portion oriented towards the base (20) of the retaining element (10).
