A closure element includes a support frame for supporting a refractory element, for example a plate, of a slide closure for use in liquid melt containers. One or a plurality of eccentrics are mounted on the support frame for detachably fastening the refractory element within the support frame. The refractory element includes a metallic sheath, and the eccentrics include eccentric surfaces bearing directly on the metallic sheath. The eccentrics are positioned such that the eccentric surfaces act on the refractory element both longitudinally thereof and transversely thereof. |
