Hook-type attaching device

A retaining device with hooks, comprising:

• an elastic film extending in a longitudinal direction presenting a top face and a bottom face;
• and
• a plastic tape extending in the longitudinal direction comprising a base presenting a bottom face and a top face and including a plurality of retaining elements extending from said top face of the base;
• the device being characterized in that
• the elastic film, the base, and the retaining elements are formed integrally by means of extrusion, and in that the elastic film presents residual deformation that is less than 30% after being lengthened by 100% of its initial dimension, and at ambient temperature (23° C.),
• wherein the plastic tape and the elastic film form an intermediate layer having a bottom face and a top face, said retaining device further comprising a layer of nonwoven material secured to the bottom face of the intermediate layer,
• wherein the layer of nonwoven material is partially encapsulated within the bottom face of the intermediate layer.
