A coaxial-cable-assembly includes a coaxial-cable and a tubular-ferrule. The coaxial-cable includes an outer-jacket and an exposed outer-shield conductor. The tubular-ferrule includes a crimp-zone, a skirt-zone, and a transition-zone therebetween. The tubular-ferrule defines a relief-slot having an open-end, a closed-end, and two parallel-edges that extend from the crimp-zone to the skirt-zone. The crimp-zone is brought into forcible contact with the exposed outer-shield conductor by drawing the two parallel-edges into close proximity, such that a crimp-zone-diameter is reduced to less than a skirt-zone-diameter. As a result, the closed-end of the relief-slot forms an aperture in a junction of the transition-zone and the skirt-zone.
