Coaxial connectors include a connector body that includes a first connector body opening for receiving a coaxial cable. A tubular inner contact post that is at least partly within the connector body is provided. A sliding compression element is also provided that is configured to impart a generally circumferential compressive force to secure one or more elements of the coaxial cable between the sliding compression element and the connector body when an axially directed force that is directed away from the connector body is applied to the coaxial cable.
