Abstract
A pipe connector comprises a split annular ring for surrounding and engaging the end portions of two pipes. The ring has a generally U-shaped radial section providing arms having inwardly extending transverse surfaces directed towards each other and which, when the ring is engaged on the pipe ends, engage outwardly extending transverse surfaces on the pipe ends. The ring is permanently engaged with one pipe and is resiliently expandable to permit engagement of the other pipe therewith, corresponding surface portions of the pipe end portion and ring being shaped so that the ring is automatically expanded as the other pipe end portion is engaged therewith. Centering and guiding means comprising a cylindrical extension on the one pipe which is received within the other pipe are provided for maintaining coaxiality between the pipes as they are brought together and the other pipe is engaged with the ring.
