ABSTRACT:
One of the ends (X) of a tube has an internal annular ledge (7) and an annular wall (9), the internal surface (9A) of which forms an annular corner (10) around the ledge (7) and widens slightly as it moves away from the ledge; the other end (Y) forms a setback (12) towards the inside followed by an approximately cylindrical collar (14) for the turns of reserve yarn, the annular edge (14A) of which is capable of bearing against a ledge (7) as described above, of a similar tube and of being centered by an annular corner (10) as described above, of a similar tube; said annular edge (14A) has hollows (16) which are capable of allowing the passage of fluid which thus acts on the turns of the reserve.
