Abstract: A continuous 360.degree. electrically conductive seal between a back shell (30) and an electrically conductive cable braid (46) is provided by a pair of coaxial sleeves (68, 74), a ferrule (56), and an annular shoulder (80), the conductive seal resulting from interference fitting between the sleeves, ferrule and back shell and the shoulder plastically deforming. Outer sleeve (68) is interference fit in ferrule (56). Inner sleeve (74) has its outer periphery interference fit within the outer sleeve and within the back shell. The annular shoulder extends outwardly from the inner sleeve to define forward and rearward facing V-shaped teeth and is comprised of a malleable material adapted to plastically deform within respective teeth extending rearwardly and forwardly from the outer sleeve and the back shell.
