    摘要: A joint for jointing the ends of two pipes, particularly lined pipes, in which a radial resilient portion extends between the two ends of the pipes, two oppositely extending axial portions at the radial inner part of the radial portion each engage within the interior of one of the two pipe ends. Construction of the joint is such that the axially extending portions of the joint are urged radially outwardly against the inner surface of the two pipe ends as the two pipe ends are drawn axially towards one another.
