A device for filling a container comprises an endpiece provided with an inner conduit equipped at its end with a ball-valve having a through passage and pivotable in the endpiece about a diametral axis transverse to the passage. An annular member having an external face coplanar with the frontal surface of the endpiece, has an inner spherical surface held in permanent contact with the external face of the ball-valve. The annular member is mounted for rotation with respect to the endpiece about the longitudinal axis of the conduit. At least part of the intersection line between the passage and the external surface of the ball-valve cooperates in cutting relationship with an edge of the external face of the annular member while the latter is rotating and the valve is pivoting to close the conduit.
