ABSTRACT:
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.
