A coaxial cable connector having a body assembly and a cap assembly which are adapted to be secured together. The body assembly has a front body with a front body cavity formed therein, an electrically conductive collet affixed at least partially within the front body cavity, an axially moveable electrically insulative seizure bushing fitted within the front body cavity, an axially moveable mandrel fitted within the front body cavity and extending beyond said front body, and a spring fitted within the front body cavity for urging the seizure bushing towards an open position. The cap assembly has a cap body with a substantially open passage therethrough, and an outer conductor clamp fitted within the passage. The front body also has a bevelled surface proximate the open end of the front body cavity for engaging and constricting the outer conductor clamp upon joining of the body assembly to the cap assembly. The outer conductor clamp has a pusher surface for moving the mandrel from its open position towards its closed position upon joining of the body assembly to the cap assembly, thereby urging the seizure bushing towards its closed position to engage and constrict the collet.
