Claim:
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.
