An operating-room-cable assembly includes a lead connector with a lead-connector housing for receiving a lead. The lead-connector housing includes a first housing element and a second housing element that slide relative to one another to transition the lead-connector housing between an open position and a closed position. A connector port is defined in the lead-connector housing and includes a first surface formed by the first housing element and a second surface formed by the second housing element. A lead retainer is disposed along the second surface and receives the lead when the lead-connector housing is in the open position. Connector contacts are disposed along the first surface. The connector contacts couple to terminals disposed along the lead when the lead is received by the lead retainer and the lead-connector housing is in the closed position. Operating-room-cable conductors are coupled to the connector contacts and extend along the elongated body.
