- This sleeve 61 may for example be made by machining on the end 1 1a of the first tube 3a which is metallic.
- This variant is very advantageous since the connection of the pipe 14 to the tube 2a will require only one crimping operation instead of two according to the previous example. Furthermore, the total length of the second connector 60 is reduced by half compared to that of the second connector 35 of the previous example. And as a result, the total mass of the second connector is also decreased with a weight saving of about 45% compared to the second connector 35 of the second variant.

- Those skilled in the art will be able to adapt the geometry of the crimping ring to the crimping operation described above.
- the third variant is also in accordance with the principle of the first and second variants.
- the second connector 80 is in the form of a sleeve 81 machined on the end 1 1 of the first tube 3. This second connector 80 and the corresponding crimping operation is described in the publication FR 2,899,307.
- the outer surface 89 of the sleeve 81 has a series of bosses 85 forming crimping zone 87 on which is applied a radial crimping force according to the arrows 86 by a suitable tool not shown which causes a permanent deformation in compression of the sleeve 81 and which causes also a concomitant deformation of the end 21 of the pipe 14 to be connected.
- the inner surface 82 of the sleeve 81 which is in contact with the end 21 of the pipe 14 comprises a portion 83 which is glued by a multicomponent adhesive one of which is encapsulated so that before crimping, this glued portion does not exert its function glue.
- the first, second and third variants are particularly advantageous since that they reduce the mass of the second connection compared to the examples described with reference to FIGS. 2 to 6, they reduce the space generated by the presence of this second connection and can be easily made by machining at the end 11a of the first tube 3a.
- FIGS. 14 and 15 describe two embodiments which do not involve a crimping zone but a second connection made of a first coupling part and a second coupling part capable of being disconnected, which results in that second fitting is removable. Furthermore, according to the invention, one or the other of the first or second parts is formed at the end 1 1a of the first tube 3a at the output of the first connector 1a.

- This first coupling portion 91 has a female frustoconical end surface 92 which coincides with the male frustoconical end surface 93 of a second coupling portion 94 machined at the end 21 of the pipe 14.
- the end surfaces 92,93 of the first 91 and second 94 parts of connection are maintained in contact support by means of a nut 95 whose inner face has a threaded zone 97 located at a threaded conjugate zone 98 made on the outer surface of the first coupling part 91.
- the tubular fluid flow zone 91a at the first coupling portion 91 and the fluid circulation tubular zone 94a at the second coupling portion 94 are coaxially disposed opposite one another in a manner that to ensure the flow of fluid through the second connector 90.
- the tightening of the nut 95 ensures the fixed retention of the first coupling portion 90 on the second coupling portion 94. On the contrary, loosening of the nut makes it possible to separate the first coupling portion 90 from the second coupling portion 94 .
- the second coupling portion comprises an annular groove 96 punctually widening the diameter of the pipe 14 and conferring on this second coupling portion 94 an elasticity allowing this second coupling portion 94 and the second coupling 90 in its entirety, to retain their properties, and in particular their sealing properties.
- the diameter of the pipe 14 is smaller than the diameter of the first pipe 3a, which necessitates the presence of a narrowing zone 99 situated at the level of the first coupling 90. It will be understood that this embodiment applies also to a configuration in which the diameters of the first tube 3a and the pipe 14 are identical. Those skilled in the art will be able to adapt the first connector 90 to such a configuration.
- the second coupling comprises a first coupling portion 100 machined at the end 11a of the first tube 3a at the outlet of the first coupling 1 a.
