Abstract
1. Internal sleeve seal for pipe joints on pipelines, comprising a collar of flexible material which fits over the seams of the joints and to both sides of the seams of the joints is held under pressure against the inside wall of the pipeline by ring-shaped tensioning elements, and in the region of the tensioning elements has a respective annular recess incorporated in its external surface and approximating in its width to the width of the tensioning ring, which recess houses an annular cushion (4) made from a material with good powers of recovery, for example rubber, which in the uncompressed state is in contact with the inside wall of the pipe and at a distance from the side walls of the recess, characterised in that the annular cushion (4) is also at a distance from the side walls of the recess when it is in the compressed state, and in that the circumferential surfaces adjoining the side walls of the recess to both sides protrude so far in the radial direction that they rest securely against the inside wall of the pipeline once the compressed annular cushion (4) has made a secure seal.
