The sleeve device is formed with a radially inwardly opening, distally contracting conical bearing surface which mounts a radially inwardly contractible gripper ring device captive therein, and constructed to be driven radially inwardly by the bearing surface as the sleeve is drawn proximally on the spigot to grip a plastic pipe trapped in the annulus between the sleeve and spigot.
