Abstract: An end connector for connecting a coaxial cable to a port having a tubular body with front and rear end portions, a cable attachment section associated with the rear end portion for attaching the connector to the cable, and a port attachment section associated with the front end portion for attaching the connector to the port. The port attachment means includes a split ferrule defining a plurality of partially cylindrical resilient fingers, the fingers having inward arcuate projections defining a circumferential ridge adapted to engage the port. The split ferrule defines an inner surface which is inwardly tapered to enhance port to connector contact. A locking sheath is disposed about the front end portion of the tubular body and is adapted to engage an outer surface of the split ferrule so as to restrict the resiliency of the resilient fingers.
