ABSTRACT OF THE DISCLOSURE A modular connector for interconnecting a coilable tubing string with a downhole electrical tool and wherein an electric signal conducting cable extends through the tubing string and through the connector. The connector includes a swivel coupling having a coupling body with a spherical socket for receiving a spherical coupling member which is connectable to the downhole tool through a cable connector body secured to the spherical coupling member. A pin disposed in the coupling body projects into a slot in the spherical coupling member to prevent rotation of the tool with respect to the longitudinal central axes of the connector and the tool. The connector includes a frangible coupling for retrieving the tubing string if the downhole tool becomes stuck. Separation of the frangible coupling exposes a fishing head for retrieving the tool. A one-way check valve in the connector body permits injection of fluid into the wellbore through the tubing string while precluding wellbore fluids from flowing in the opposite direction up through the tubing string. The connector body is adapted to be connected directly to the downhole tool if the swivel coupling is not required.
