A connector having a front end for attachment to a terminal and a back end for attachment to a coaxial cable includes a body, a post mounted within the body; and a contact assembly movably mounted within the post and body. The contact assembly includes a guide, a contact mounted to the guide, and preferably a clip mounted to the contact for making electrical and mechanical connection with the center conductor of the coaxial cable and a sabot. The contact assembly moves longitudinally toward the front end of the connector, such that the front end of the contact moves from a first position completely within the body to a second position proximate the connector interface, as the connector receives the coaxial cable. Preferably, the guide has an opening for the center conductor, which is viewable to a user during attachment until the center conductor enters the opening. The sabot moves with the contact assembly in a telescoping fashion enabling a greater distance of axial displacement. In addition, the contact assembly preferably contains a means to prevent the cable from being forced backward after installation.
