Shroud for casting metal from a ladle, said nozzle comprising. (a) a bore extending parallel to a first longitudinal axis, X1, from an inlet orifice to an outlet orifice, (b) an inlet portion located at an upstream end of the ladle shroud and consisting of a plate comprising: - a planar upstream surface normal to said longitudinal axis, X1, said upstream surface comprising said inlet orifice and being defined by an upstream perimeter, - a downstream surface defined by a downstream perimeter and separated from the upstroam surface by, - a peripheral wall contiguous to both upstream and downstream perimeters defining the thickness of the plate at the level of the upstream perimeter, and comprising at least a first and a second gripping portions separated from each other by the bore, (c) a tubular portion extending along said first longitudinal axis, X1, from said downstream surface of the inlet portion to a downstream end, opposite to the upstream end, and where said outlet orifice is located, characterised In that, each of said first and second gripping portions of the peripheral wall comprises an upstream protrusion culminating at an upstream ridge separating a leading edge facing towards the upstream end of the ladle shroud from a trailing edge facing towards the downstream end of the ladle shroud, and protruding out beyond the whole peripheral wall of the corresponding gripping portion, said upstream portions extending parallel to the upstream surface and symmetrically to one another with respect to the longitudinal axis, X1, along the respective first and second gripping portions and in that, - said leading edge forms with a plane parallel to the upstream surface an angle, α1, and - said trailing edge forms an angle, β1, with a plane parallel to the upstream surface, wherein |α1| ≥ |β1|.
