Abstract
A configuration for sealing or sound-proofing cavities, for example in the vicinity of a chassis or a body of a motor vehicle, includes two half-shells which are separately produced, which can be locked together and which, in an interlocked state, form a free, outwardly open ring-shaped gap in an outer, intermediate peripheral edge region. The ring-shaped gap is inwardly limited by an inner contour on one of the half-shells. A heat-expansible element as a contoured ring-like plate has a form which substantially corresponds to that of the ring-shaped gap formed between the two half-shells on their outer wall. The configuration is material-saving and can be produced and mounted at low cost.
