An assembly for connecting a coaxial cable end to a threaded port and having a fitting to which an end of a coaxial cable can be connected. A nut, joined to the fitting, has a first set of threads and is turnable in a tightening direction around a central axis of the connecting assembly to progressively engage the first set of threads with a second set of threads on a port. The nut has an outer surface at which a first edge, facing circumferentially in a first direction, is defined. A sleeve surrounds the nut and has a body with a first reconfigurable finger extending in a circumferential direction and upon which a second edge, facing circumferentially oppositely to the first direction, is defined. The second edge is brought into bearing engagement with the first edge as the sleeve is turned in the tightening direction around the central axis so that the nut follows movement of the sleeve. The sleeve is movable continuously relative to the nut around the central axis in a loosening direction.
