A quick-locking male connector includes: an inner contact; an insulator; an outer contact; a spring basket with a plurality of spring fingers; an elastic claw with at least radially-inward one tooth and a radially-outward nub; a connector body attached to the outer contact; and a coupling nut having at least one radially-inward extending nub. The coupling nut is movable between a rear unsecured position, in which the nub of the coupling nut is rearward of the nub of the claw, and a forward secured condition, in which the nub of the coupling nut engages the nub of the claw and forces the at least one tooth of the claw radially inward to engage with a thread of an outer conductor body of a mating female connector. The spring fingers of the spring basket apply radially-outward pressure to the outer conductor body of the mating female connector.
