Abstract

A connecting assembly for an end of a coaxial cable and having a first element, that is turned around a first axis in a first rotational direction to progressively tighten the first element to a connector, and a housing. The connecting assembly further has: a) an axially elongated first groove in one component; and b) an axially elongated first finger on a second component that resides within the first groove with the connecting assembly in a first state. With the connecting assembly in the first state, turning of the housing in the first rotational direction causes the first finger to cause driving of the first element with a torque up to a predetermined torque. Continued turning of the housing with a torque exceeding the predetermined torque causes reconfiguration of the connecting assembly in a manner whereby the first finger moves circumferentially out of the first groove.

11. (canceled)

18. A connecting assembly for an end of a coaxial cable, the connecting assembly comprising:

a first internally threaded element that is turned around a first axis in a first rotational direction to progressively threadably tighten the first element to a connector;

a housing having an exposed surface that can be engaged by a user and turned around the first axis;

the circumferential surface of the first finger and first groove nominally matched in shape as viewed in cross section taken transversely to the first axis,

with the connecting assembly in the first state, turning of the housing in the first rotational direction causes the first finger within the first groove to drive the first element in the first rotational direction with a torque up to a predetermined torque,

whereupon continued turning of the housing in the first rotational direction with a torque exceeding the predetermined torque causes reconfiguration of at least one of the first finger and surface bounding the first groove whereby;
