Abstract
A method and apparatus for producing a pipe connection are disclosed. The apparatus includes an inner pipe formed on the pipe to be joined which has a widened end part. An outer pipe in the pipe connector is dimensioned to receive the inner pipe and has an undercut formed therein to receive the widened end part. A sleeve is mounted inside the inner pipe with a close tolerance so as to be substantially free from play. The sleeve has a widened wedge-shaped portion which engages the inner pipe internally. As a result, the inner pipe is retained between the undercuts and the wedge-shaped portion of the sleeve.
