<p>A device comprising a socket portion (1) secured to a rigid nozzle (2) and provided with a tiered bore including a large-diameter section (13) beyond an axial locking member (15) that can be moved between two positions, and a tightening ring (14) releasably fitted within the large-diameter section (13) and provided on its inner surface with at least one catch (25) forming a means for axially connecting a tube (7) to the tightening ring (14) by engaging the outer tube surface. In one of its two positions, the axial locking member (15) prevents axial movement of the tightening ring (14) away from the rigid nozzle (2), while in its other position, it releases said ring.</p> |
