The invention concerns a device for filling a liquid tank (1) provided with a tubular connecting piece (2) extending outwards, said device comprising: a flexible filling hose (3) whereof the first end is inserted into the connecting piece (2) having on its outer surface a circumferential rib (4) arranged in the proximity of its first end; at least a cylindrical sealing joint (5) arranged coaxially between the hose (3) and the connecting piece (2), and whereof the axial position is located between the hose rib (4) and a circumferential ledge (9) inside the connecting piece; a clamping component (6), arranged coaxially outside the connecting piece (2), provided with locking means (7) for blocking it relative to the connecting piece (2), provided with a circumferential projection (8) oriented inwards, located in the proximity of its end furthest from the tank; said projection (8) of the clamping component (6) enabling to apply directly or indirectly axial pressure on the circumferential rib (4) of the hose towards the tank, thereby causing axial compression of the sealing joint (5) between the circumferential rib (4) of the hose and the ledge (9) inside the connecting piece (2) so as to provide a sealed connection between the connecting piece (2) and the hose (3).

Dispositif de remplissage d'un réservoir pour liquide (1) muni d'un embout tubulaire (2) s'étendant vers l'extérieur, ledit dispositif comprenant: une tubulure de remplissage flexible (3) dont une première extrémité s'insère dans l'embout (2), présentant sur sa surface extérieure une nervure circonférentielle (4) disposée à proximité de sa première extrémité; au moins un joint d'étanchéité cylindrique (5) disposé coaxialement entre la tubulure (3) et l'embout (2), et dont la position axiale se situe entre la nervure (4) de la tubulure et une corniche circonférentielle (9) intérieure à l'embout; une pièce de serrage (6), disposée coaxialement à l'extérieur de l'embout (2), munie de moyens de blocage (7) permettant de l'immobiliser par rapport à l'embout (2), munie d'un ressaut circonférentiel (8) dirigé vers l'intérieur, situé à proximité de celle de ses extrémités qui est la plus éloignée du réservoir; ledit ressaut (8) de la pièce de serrage (6) permettant d'exercer directement ou indirectement une pression axiale sur la nervure circonférentielle (4) de la tubulure en direction du réservoir, provoquant ainsi la compression axiale du joint d'étanchéité (5) entre la nervure circonférentielle (4) de la tubulure et la corniche (9) intérieure de l'embout (2), de manière à assurer un raccordement étanche entre l'embout (2) et la tubulure (3).
