Fiber-optic cable with reinforcement for lining a groove

1. A retaining device for retaining a fiber-optic cable, the retaining device comprising:

a receiving part made of a fabric and including:

an elongated hollow part configured to receive the fiber-optic cable; and

a projection extending away from the hollow part, when viewed in a cross-section,

wherein the elongated hollow part and the projection are integral components of the receiving part; and

a retaining element extending away from the hollow part, when viewed in the cross-section, the retaining element:

including a plastic strip,

being connected with the projection, and

being configured to be inserted into a groove.

2. The retaining device according to claim 1 , wherein the retaining element includes a geometric structure configured to interlock with the groove.

3. The retaining device according to claim 1 , wherein the retaining element has an adhesive side.

4. The retaining device according to claim 1 , wherein the retaining element has a hook strip.

5. The retaining device according to claim 1 , wherein a thickness of the retaining element is in a range of 0.5-2 mm.

6. The retaining device according to claim 5 , wherein the thickness of the retaining element is about 1 mm.

7. The retaining device according to claim 1 , wherein a width of the retaining element is in a range of 5-20 mm.

8. The retaining device according to claim 7 , wherein the width of the retaining element is about 10 mm.

9. A fiber-optic cable device comprising:

a retaining device according to claim 1 ; and

a fiber-optic cable inserted in the hollow part.

10. A method for mounting a fiber-optic cable, comprising:

preparing a retaining device according to claim 1 ;

inserting the retaining element into the groove; and

inserting the fiber-optic cable into the retaining device.

11. The method according to claim 10 , wherein inserting the fiber-optic cable into the retaining device includes inserting the fiber-optic cable into the retaining device before or after inserting the retaining element into the groove.

12. The method according to claim 10 , further comprising:

inserting a mounting device into the groove before inserting the retaining element into the groove; and

retracting the mounting device after inserting the retaining element.

13. The method according to claim 12 , wherein inserting the retaining device includes inserting a bar having a width a width of about 20 mm and a thickness of about 1 mm.

14. The method according to claim 12 , wherein:

the retaining element has an adhesive side or a hook side, and

inserting the retaining element includes inserting the retaining element while preventing the adhesive side or the hook side from contacting a side of the groove by using of the mounting device.
