The invention relates to a method in which provision is made of a first assembly (10) comprising a field of gripping elements (12) and a second assembly (20) provided with holding means (22) designed to engage with the gripping elements (12) of the first assembly (10) in order to realize touch and close attachment. The first and second assemblies are brought into contact such that the gripping elements (12) of the first assembly and the holding means (22) of the second assembly realize touch and close attachment. A treatment zone of the touch and close attachment is treated so as to deform the gripping elements (12) of the first assembly (10) and/or the holding means (22) of the second assembly (20) with the result that the first and the second assembly (10 20) are definitively secured and thus form a joined structure.
