4. The apparatus of claim 3, wherein the thickness is less than 0.5 cm.

5. the apparatus of any preceding claim, further comprising:

The cylindrical body comprises a plurality of body portions, each body portion providing a respective section of the cylindrical body.

6. The apparatus of any preceding claim, further comprising:

each fixation element includes a threaded hole in the cylindrical body.

7. The apparatus of claim 6, wherein the threaded hole is a blind hole or a through hole.

8. The apparatus of any preceding claim, further comprising:

a respective circular sealing element located in each recessed area.

9. The apparatus of any preceding claim, wherein at least one region of the cylindrical fitting body is electrically conductive.

10. the apparatus of claim 9, wherein the region of the cylindrical fitting body comprises an entirety of the fitting body.

11. The apparatus of claim 10, wherein the region is formed of a metallic material.

12. The apparatus of any preceding claim, wherein the cylindrical fitting body comprises an anode fitting collar.

13. A method of manufacturing a flexible pipe body, comprising the steps of:

a tensile protection metal wire layer is arranged by spirally winding a tensile protection metal wire on the underlying layer;

Providing at least one substantially cylindrical fitting body over the tensile armour wire layers, the fitting body comprising first and further spaced openings at respective ends of the fitting body and a substantially cylindrical inner surface and at least one fixing element in the outer surface between a plurality of spaced apart recessed regions; and

and an outer sheath is arranged above the assembly main body and the tensile protection layer.

14. The method of claim 13, further comprising:

the fabrication body is disposed over the tensile armour wire layer by locating at least two mating fabrication body portions over the tensile armour wire layer.

15. The method of claim 14, further comprising:

Securing the fitting body portions together to form the substantially cylindrical fitting body.

16. The method of any of claims 13 to 15, further comprising:

Wrapping a strip layer over and/or under the tensile armour wire layer and the assembled body.

17. The method of any of claims 13 to 16, further comprising:

A marking or a plurality of markings are provided on the outer surface of the outer sheath at respective positions relative to the fixing elements of the cylindrical fitting body.

18. The method of any of claims 13 to 17, further comprising:

The cylindrical assembling main body is arranged on the outer surface of the tensile protection layer, and therefore the assembling main body is in interference fit with the outer surface of the tensile protection layer.

19. The method of any of claims 13 to 18, further comprising:

The mounting body is provided in one or more body portions, at least one body portion comprising a metal region.

20. The method of claim 19, further comprising:

The fitting body is provided in a plurality of body portions, each of which is entirely made of a metal material.
