The invention relates to a seal for pipe joints between opposing walls of two interlocked pipes (1, 2), comprising a base body (13), at least one displaceable sealing element (10, 11) which is located on the base body and a soluble fixing element (12) for fixing the sealing element (10, 11) in one position. The sealing element has a self-aligning force in said position, whereby the sealing element can be released from its fixed position by the dissolution of the fixing element (12). |
