Abstract
A connector is provided for interconnecting a coaxial cable to an electrical device. The connector has an internal body and an external body which are assembled together, and which can be activated to clamp upon and seal to an inserted coaxial cable without disassembling the external body from the internal body. The external body includes a deformable inner collar that permits the connector to be attached and sealed to cables of varying thickness as are found on common single foil and braid cable, Tri Shield cable and Quad Shield cable.
