Abstract
A seal for closing a gap which is present between a tubular housing member and a plate-shaped closing member pivotally mounted within the housing member in the closing position of the closing member includes two resilient sealing lips which, even when unstressed, assume substantially symmetrical curved configurations; when the closing member assumes its closing position, the sealing lips, which have an effective width exceeding that of the gap and which are detachably mounted on the housing member, are stressed and press against the closing member to seal the gap against penetration of media therethrough in either direction. The sealing lips surround the closure in an annular manner and are made of a metallic material.
