## Abstract

A retaining device includes an elastic film extending in a longitudinal direction, and a plastics tape extending in the longitudinal direction having a base presenting a bottom face and a top face and including a plurality of retaining elements extending from the top face, the device being characterized in that the film, the base, and the retaining elements are formed integrally by extrusion.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

A retaining device according to claim 1, wherein the elastic film, the base, and the retaining elements are formed integrally by successive and/or simultaneous extrusion operations.

### Claim 3 (depends on 1)

A retaining device according to claim 1, wherein a junction between the elastic film and the base of the plastic tape, beside the top face of the elastic film and the top face of the plastic tape and/or the bottom face of the elastic film and the bottom face of the plastic tape, is continuous.

### Claim 4 (depends on 1)

A retaining device according to claim 1, wherein the partial encapsulation is performed in the elastic film of said intermediate layer.

### Claim 5 (depends on 1)

A retaining device according to claim 1, wherein the partial encapsulation is performed in the plastic tape of said intermediate layer.

### Claim 6 (depends on 1)

A retaining device according to claim 1, wherein the support layer is secured to the top face of the elastic film by means of adhesive.

### Claim 7 (depends on 1)

A retaining device according to claim 1, wherein at least one of the bottom face and/or [[of]] the top face of the intermediate layer presents elements projecting from said at least one of the bottom face and/or the top face of the intermediate layer, which projecting elements are distinct from the retaining elements.

### Claim 8 (depends on 7)

A retaining device according to claim 7, wherein the projecting elements are in the form of spikes.

### Claim 9 (depends on 1)

A retaining device according to claim 1, wherein the base of the plastic tape presents a thickness lying in the range 10 μm to 700 μm, where the thickness is the distance between the top face and the bottom face of the base, and wherein each of the retaining elements is constituted by a stem and by a head, the stem having a bottom end connected to the base, and a top end opposite from the bottom end, the head surmounting the top end of the stem, and having a bottom face facing towards the base and a top face opposite from the bottom face, and wherein the top face of the head of each retaining element includes a rib.

### Claim 10

A retaining device according to claim [[4]] 1, wherein the nonwoven material is activated.

### Claim 11 (depends on 1)

A retaining device according to claim 1, further comprising a support layer made of nonwoven material secured to the top face of the elastic film.

### Claim 12 (depends on 1)

A retaining device according to claim 1, wherein the bottom face of the intermediate layer includes the bottom face of the base and the bottom face of the elastic film, and the top face of the intermediate layer includes the top face of the base and the top face of the elastic film.
