ABSTRACT:
A fitting for connection to a metal plain end pipe includes a generally cylindrical socket section sized to receive and cradle a pipe end portion, an annular seal in the socket section for forming a fluid-tight connection between the pipe end portion and fitting, and a locking device extensible into the socket section for securing the pipe end portion to the fitting. The socket section has a first bore extending from an exterior surface substantially through the socket wall and a coaxial, second bore of lesser diameter than the first bore extending the remainder of the way. The locking device includes a shaft having a head end and an opposite tip end for extension through the first and second bores and inwardly of the socket wall interior surface for engagement with a wall of a pipe end portion positioned in the socket section. A ring seal around the shaft engages a side wall of the first bore for providing a fluid-tight engagement between the shaft and the side wall. A coil spring sleeved on the shaft urges the tip end inwardly of the interior surface and into engagement with the pipe end portion whereby the pipe is locked to the fitting.
