Abstract
Abstract A pipe or conduit coupling assembly having a pair of confronting, fluid-conveying members, a longitudinally split coupler removably circumferentially surrounding the fluid-conveying members to limit displacement of the fluid-conveying members away from each other, and at least one electrically conductive spring metal jumper mounted exteriorly on the coupler to complete an electrical circuit between the fluid-conveying members. A special retainer and toggle clamp assembly extends circumferentially around the split sections of the coupler and has a special toggle clamp which is incapable of being improperly latched to releasably secure the split sections of the coupler in place. A special safety lock is provided to prevent inadvertent release of the toggle clamp.
