ABSTRACT:
The disclosure is directed to a pre-assembled liquid tight connector for use with flexible metallic conduit. The connector is comprised of a one piece body member having a grounding member formed integrally therewith. Additionally, the body member is so constructed as to retain a resilient polyurethane collar in a pre-loaded position so that after assembling the ground conductor to the flexible metallic conduit, the collar is simply pried from the pre-load position and a liquid tight seal is achieved.
