Summary:A method and apparatus for restraining pipe against both internal and external forces at a pipe or fitting connection and to join and seal at least two pipes to form a pipeline is shown featuring an improved restraining and sealing mechanism. The restraining and sealing mechanism includes a circumferential housing and a companion sealing ring which are received within a mating groove provided in the belled end of a female pipe. The cucumferential housing has an interior region which contains a gripping ring insert. The sealing ring and housing are integrally located within a belled pipe end during belling operations. L'invention concerne un procédé et un appareil de retenue d'un tuyau contre les forces internes et externes exercées au niveau d'une connexion de tuyau ou de raccord, et connectant et scellant au moins deux tuyaux de manière à former une canalisation, se caractérisant par un mécanisme de retenue et d'étanchéité amélioré. Le mécanisme de retenue et d'étanchéité comprend un logement circonférentiel et une bague d'étanchéité associée reçus dans une rainure correspondante situé dans la tulipe d'un tuyau femelle. Le logement circonférentiel présente une zone intérieure contenant un insert annulaire de préhension. La bague d'étanchéité et le logement sont intégrés à la tulipe d'un raccord lors des opérations de formation de la tulipe.
