An axially compressible F-connector for conventional installation tools for interconnection with coaxial cable includes a rigid nut with a rear skirt forming a socket. A rigid, tubular post penetrates the nut and engages coaxial cable. An internal, slidable sleeve has a plug portion that is adapted to engage and seat within the socket. A tubular end cap completes the assembly. The tubular post coaxially extends through the connector, physically connecting the nut and coaxial cable it engages. However, grounding is insured by portions of the cable sheath that are sandwiched within the socket between the sleeve plug and the nut skirt by sealing O-rings affixed to the sleeve plug.
