A connection device of a female pipe and a male pipe, with a head which is configured to be accommodated in a receptacle of the female pipe, and comprising a peripheral groove in which a seal is accommodated. The male pipe comprises at least one extension which is configured to limit the pivoting of the male pipe around an axis of rotation which is perpendicular to the longitudinal axis of the female pipe. This configuration makes it possible to limit the risks of damaging the seal.

An assembly including a first pipe length and a second accommodating mechanical pipe length, said first length being assembled in said second length by means of an interface joint, that is a conductor of electric current. As it is assumed that said first length and said second length are also conductors of electric current, the joint thus provides good sealing between the first pipe length and the second pipe length in order to prevent leakages of fluid and to prevent the formation of inopportune electric arcs due, for example, to static electricity.

In an aircraft duct formed with pipes connected in pairs via connectors in which the pipes are mounted with the possibility of axial displacement, there exists a risk that a pipe of the duct, with a dimension greater that the dimension of the nominal pipe, is mounted instead and in place of the latter. In this case, the wrongly mounted pipe would risk not having sufficient clearance in axial translation. In order to solve this problem, it is disclosed to equip one of the relevant connectors with an obstacle limiting the travel of the nominal pipe and preventing the mounting of a pipe with a greater dimension belonging to the duct. A method for assembling an aircraft portion is also proposed, in order to benefit from the particularities of the duct.
