The device has a metal collar (4), which engages over the top of the aperture, and an elastic fastener ring, fastened to the collar. The ring is a self-tensioning ring disc, and consists of a meander-like closed band. Its length is elastically adjustable over its complete radial width. When not tensioned, the band of the ring disc extends on a conical surface. A heat-resistant or sealing material is positioned between hob and metal and metal collar, and between hob and fastener ring. The material is a ceramic fibre material.
