A mechanical joint comprising:
- a piping element defining a first flange and a socket, the socket formed proximate the first flange;
- a pipe extending into the socket and defining an outer surface;
- a gland assembly comprising:
- a gland defining a gland bore, the pipe extending through the gland bore;
- a joint restraint assembly comprising a gripper and a spring, the gripper configured to engage the outer surface of the pipe, the spring configured to bias the gripper towards engagement with the outer surface of the pipe, wherein the joint restraint assembly is configurable in a deactivated configuration, wherein the gripper is prevented from engaging the outer surface of the pipe, and an activated configuration, wherein the gripper is able to engage the outer surface of the pipe;
- and
- a gasket defining a recess, the spring configured to engage the recess;
- and
- a deactivation mechanism configured to engage the gripper and bias the gripper away from the outer surface of the pipe in the deactivated configuration.
