Abstract
Abstract This invention relates to the transfer of liquid products, having special application to oil drums and including a pouring spout which is characterized by an attachment which is extended, on the opposite side to the inlet cross-section of an oblong opening, by a chute connected to the attachment by an articulation zone perpendicular to its longitudinal axis, the chute being provided with catch-type assembly members which co-operate with complimentary members carried by the attachment and which together ensure the maintenance and immobilization of the chute in a direction differing from that of the attachment.
