A housing carries a male push-lock precision BNC connector. The function of the BNC latch of the male connector carried therein is performed by a spring-biased lock ring captive in a housing and that fits snugly and concentrically over a male sleeve, resulting in a double shell of two rigidly attached cylindrical portions that are coaxial, coextensive, yet separated to accept a BNC female shell. The double shell is held captive by anchoring it to the inside of the housing. The male sleeve has a slot and/or cut-away portion to accept the forward travel of the bayonet pins, which, when the connector halves are engaging, extend beyond the thickness of the sleeve and into the region occupied by the lock ring. The lock ring has grooves having various portions that engage the bayonet pins. As the housing containing these male parts is without rotation moved toward the female connector, the lock ring rotates as the grooves contact the bayonet pins. After sufficient angular rotation the grooves allow the two connector halves to approach each other without further rotation of the lock ring. After the male and female halves are essentially fully mated along the axial direction, the grooves clear the bayonet pins, and a bias spring rotates the lock ring, whose grooves now present a path at right angles to the axial path. The lock ring now blocks the separation of the connector halves. To create the tension needed to draw the precision BNC connector parts firmly together, the grooves resume a shallow angled path (ramp). The bias spring continues to provide the force to rotate the lock ring. Eventually the bayonet pins resist any further motion of the lock ring. The lock ring has a thumb tab that extends out from the housing to allow the motion of the lock ring to be reversed when removing the push-lock connector.
