The present invention relates to a clamping device including at least two assemblies each composed of a clamp (10) pivoting about a horizontal axis (11) and fitted with a groove (12) receiving a shoe (13) generally cylindrical in shape incorporating a flat surface (14) parallel to the axis of said cylinder, said shoe being capable of pivoting in the groove.The present invention also relates to a one-piece inner nozzle (2) particularly adapted for use with this clamping device. The one-piece inner nozzle according to the invention is thus composed of a tubular part (6) defining a pouring channel (4) and a flat part or plate (7) providing contact with the downstream component (8) of the pouring channel. The characteristic of the nozzle according to the invention is that the plate (7) is generally shaped as a prism which can be defined by its polygon-shaped bases and the prismatic surface which they intersect perpendicularly, the said polygonal bases comprising an upper base (22), whose displacement within the prismatic surface defines the interface with the tubular part (6) and a lower base (21) parallel to the upper base and, on either side of the upper base, two sides (23, 23') forming an obtuse angle (alpha) with the upper base (22). |
