A cable assembly for a patient treatment system comprises an electrical cable having a proximal connector configured to connect to an external electrical stimulator device and a distal connector including a distal housing having an open distal end. The distal housing houses a manifold that supports a plurality of spring-loaded electrical contact assemblies aligned in two rows and being electrically connected to a corresponding one of a plurality of electrical contacts in the proximal connector. The housing distal open end is closed by a header that is movable between a closed position resting on the housing open end and an open position spaced there above. The header has a pair of side-by-side longitudinally extending openings. With the header in the open position, a practitioner holds the distal connector in one hand and with the other hand inserts the distal electrical contacts of one or two therapy delivery devices into the longitudinally extending openings. The practitioner then moves the header into the closed position to bring the distal electrical contacts of the therapy delivery devices into firm electrical contact with the spring-loaded electrical contact assemblies housed inside the distal housing.
