description A sliding closure (1) for a metallurgical vessel is provided with a slider unit (7), a refractory closure plate (3) which can be inserted therein, a refractory exchangeable nozzle (4), which can be connected to the closure plate (3), with an upper face side (15) and an outlet opening (24) and a securing means (8). By means of these securing means (8), the exchangeable nozzle (4) can be pressed against a stop element (9) in the slider unit (7). This stop element (9) in the slider unit (7) and the exchangeable nozzle (4) are each configured with contact surface (16, 17), which tapers conically against the sliding plate (3), in such a way that, in the installed state, they are pressed against one another in a corresponding manner, with a refractory sealing material between the exchangeable nozzle (4) and the sliding plate (7). As a result, an improved axial and lateral fixing is achieved between these, and, as a further result, the risk of breakthrough is reduced.
