A connector for an electrostimulation lead includes a connector housing defining a fastener aperture, a septum disposed over the fastener aperture, and a fastener for mating with the fastener aperture to secure a received lead to the connector housing so that at least one terminal disposed on the received lead electrically couples with at least one conductor contact disposed in the connector housing. The septum includes a septum flap and an attachment cuff. The septum flap is configured and arranged for extending over the fastener aperture and for receiving a tool for folding the septum flap open to expose the fastener aperture. The attachment cuff is configured and arranged for coupling the septum flap to the connector housing. The fastener is configured and arranged to be disposed in the fastener aperture and to be tightened against the lead to hold the lead within the connector housing.
