Zusammenfassung:	The invention resides in a fastening means for a closure plate on a sliding shutter for the outlet of a vessel containing molten metal, whereby the closure plate can be fixed within a supporting frame by the action of releasable gripping means which are provided on the supporting frame and which act on a metal sheath which at least encircles the periphery of the closure plate. The closure plate's external periphery is provided with at least one recess into which the sheath is pressed as a result of the deformation produced by the gripping means. According to an alternative embodiment of the invention, the sheath encircles the exterior periphery of the closure plate as a narrow tension band and is provided with at least one tightener. The desired pretensioning of the sheath and the fixing of the closure plate and sheath to the supporting frame is effected in combination with the tightener.
