Abstract
For sealing an annular space or space ( ) between an opening ( ), in a wall or similar member ( ), and an object ( ) extending through the opening ( ), at least one sealing element ( ) is placed in the annular space ( ). Initially, the sealing element ( ) is placed in the compressed state between the wall ( ) and the object ( ) and subsequently is released from the compressed state to an expanded state. For this purpose at first, the sealing element ( ) is compressed by a sheath ( ) which, after the sealing element ( ) is positioned in the annular space ( ), is destroyed and makes the expansion of the sealing element ( ) possible.
