The sleeve assembly receives a coaxial cable to insert therein from a rear end thereof in such a way that an insulator layer of a front end of the coaxial cable is set substantially flush with a front end of the tube and the sleeve assembly is then acted upon by a force applied by a tool to drive the metal collar frontward against the contact section of the sleeve for breaking and separating the retention section of the sleeve from the sleeve to further move frontward along a surface of the buffering section of the sleeve. Due to a constraint imposed by the metal collar, the buffering section is compressed downward to enhance tightness of engagement between the coaxial cable and the connector.
