Pipe connecting device

A pipe connector comprising an elongated plastic body having a bore therethrough, one end of the body having means enabling coupling of the bore at the end to a fluid port, the other end of the body comprising a first spigot portion coaxial with the bore and a second coaxial spigot portion separated from the first spigot portion by a step, each of the spigot portions being of substantially cylindrical form, each with a first protruding circumferential rib at the end of the respective spigot portion and a second protruding circumferential rib between the end of the respective spigot portion but spaced inwardly therefrom, the second spigot portion having a larger external diameter than the first spigot portion;

• and deformable metal sleeve normally having coaxial cylindrical inner and outer surfaces disposed on the second spigot portion, swaged over said ribs on the second spigot portion to strengthen the connector and to provide a seal against leakage, and projecting over the first spigot portion to define an annular cylindrical cavity between the sleeve and the first spigot portion, the inner surface of said metal sleeve being, in its unswaged portions, of larger diameter than the external diameter of the circumferential ribs on the second spigot portion, and said sleeve being adapted to be swaged to engage a hose positioned in the annular cylindrical cavity.
