In order to couple in a tight and dismantlable manner the ends of two fixed, rigid tubes (10, 12), more particularly in an aircraft fuel transfer circuit, use is made of a connecting sleeve (20), whereof a first end is tightly fixed by means of a nut (30) to a half-coupling (28) welded to a first (10) of the tubes. The second end (20c) of the sleeve can tightly slide on the other tube (12), which gives access to a device (40) connecting two internal tubes (14, 16) in a double envelope circuit.

A dismantlable external device for the tight coupling of first and second external tubes, surrounding first and second internal tubes connected by a dismantlable internal coupling device, said dismantlable external device comprising a connecting sleeve and means for the tight fixing of a first end of said sleeve to the first external tube, a second end of the connecting sleeve being in tight contact with the second external tube, in such a way that the sleeve can slide on the latter following the dismantling of the tight fixing means, thus allowing a free access to the dismantlable internal coupling device.
