The invention claimed is: 1. An electrical insulation system for a linear element forming part of a fluid system subjected to risks of possible external electrical discharges, the electrical insulation system comprising an insulation insert (12) between two parts (14, 16) of said linear element, each part having an external surface, characterized in that: a) said parts (14, 16) have grooved edges comprising diametric grooves and longitudinal grooves on said external surface, b) the insulating insert (12) is a piece of insulating material formed between said parts (14, 16) such that it provides an internal duct for the passage of fluid between said parts (14, 16) and covers said grooved edges, assuring the leak-tight joint of the insulating insert (12) with said parts (14, 16) without needing specific sealing means for it. 2. An electrical insulation system for a linear element forming part of a fluid system according to claim 1, wherein the formation of the insulating insert (12) is carried out by means of an injection technique using a suitable mold. 3. An electrical insulation system for a linear element forming part of a fluid system according to claim 1, wherein the material of the insulating insert (12) is chosen from PEEK, polyamide, and nylon. 4. An electrical insulation system for a linear element forming part of a fluid system according to claim 1, wherein the area (18) of the insulating insert (12) located between the edges of said part (14, 16) has a minimum length of 25 mm. 5. An electrical system for a linear element forming part of a fluid system according to claim 1, wherein the linear element is a metal pipe. 6. An electrical insulation system for a linear element forming part of a fluid system according to claim 1, wherein the fluid system belongs to an aircraft. 7. An electrical insulation system for a linear element forming part of a fluid system according to claim 6, wherein the fluid system is a fuel system. 8. An electrical insulation system for a linear element forming part of a fluid system according to claim 7, wherein said parts (14, 16) include bonding point elements (26, 28) 9. An aircraft pipe system for transporting fluids within an aircraft comprising electrically conductive pipe units electrically insulated from each other and having located between such pipe units an electrical insulating element of at least 25 mm length wherein said pipe units have grooved edges comprising diametric grooves and longitudinal grooves; and said insulating insert (12) is a piece of insulating material formed between said pipe units (14, 16) such that it provides an internal duct for the passage of fluid between said parts (14, 16) and covers said grooved edges, assuring the leak-tight joint of the insulating insert (12) with said parts (14, 16)
