A connector includes: a first portion; a second portion; and a cable gripping portion. The cable gripping portion is structurally configured to allow rotation of the cable gripping portion relative to the second portion in a second rotational direction to permit tightening of the second portion to a third portion; and the cable gripping portion is structurally configured to engage the second portion to prevent the cable gripping portion from rotating relative to the second portion in a first rotational direction so as to permit a coaxial cable to be rotated relative to the cable gripping portion while inserting the coaxial cable into the connector.
