Claim:
1. An assembly device between a first section and a second section of a doubleskinned fuel pipe of an aircraft, said device comprising: a clamp allowing one end of an internal pipe of the first section to be assembled with one end of an internal pipe of the second section; a coupling device allowing one end of an external pipe of the first section to be assembled with one end of the external pipe of the second section; and a fitting extending between the end of the external pipe of the first section and the end of the external pipe of the second section and having a shape complementary to the shape of an internal portion of the coupling device, wherein, when the first section and the second section of the fuel pipe are assembled by the assembly device, the section of the fitting through any cutting plane perpendicular to a longitudinal axis common to the coupling device, the external pipe of the first section and the external pipe of the second section contains the smallest surface delimited by: a line corresponding to the intersection of the internal surface of the coupling device with the cutting plane and, a straight line cutting said line at two points, the straight line being tangential to the orthogonal projection in the cutting plane, of the internal surface of the external pipe of the first section or of the external pipe of the second section.
