A connector assembly located at the proximal end of an elongated lead body includes first and second electrical contacts, each attached to a respective one of at least two conductors. An interlocking construction positively joins the first and second electrical contacts and maintains a fixed axial spacing therebetween. The first connector includes a connector pin having a head portion at an extremity thereof and an integral and coaxial tail portion and the second connector includes a connector ring coaxial with and telescopingly received on the tail portion. An electrically insulative male joint member integral with the tail portion is selectively lockingly engageable with a female joint member integral with the connector ring. Diametrically opposed knob members project radially from an outer peripheral surface of the male joint member and slidably engage a pair of diametrically opposed longitudinal slots in an integral axial sleeve extending proximally from the second electrical contact, the longitudinal slots terminating at a pair of oppositely extending circumferential slots. The electrical contacts are positively joined by axially aligning the connector pin and the connector ring while spaced apart, then advancing on axis the tail portion of the connector pin toward the connector ring so that the outer peripheral surface of the male joint member is fittingly engaged with the inner peripheral surface of the axial sleeve and so that the knob members are slidably engaged with the longitudinal slots, then rotating the tail portion so that the knob members are slidably engaged with the circumferential slots.
