A coaxial cable and an electrical connector therefor including a back-nut threaded to a body to receive a female fitting. The body has a stop for the back-nut. The back-nut has an internal shoulder. The body has an internal frusto-conical surface. A conductive ferrule is also provided. A cylindrical member clamps a cylindrical portion of the ferrule to the cable outer conductor. The ferrule has a shoulder. The ferrule also has a slotted frusto-conical surface to fit against the frusto-conical surface of the body. The slots form spring projections that are held in pressure contact with and in good electrical contact with the said body surface. The back-nut shoulder pushes the ferrule toward the body as the back-nut is threaded thereto. The back-nut has a flange behind which a gasket gland is retained. The clamping member is held in axial compression between the ferrule shoulder and the gasket gland. The gasket gland then provides a seal between the back-nut and the cable, the cable being surrounded by the flange.
