Couplings for implanted leads and external stimulators, and associated systems and methods

A connector attached to an electrical cable in a patient treatment system for delivering therapy to a patient, the connector comprising:

• a first housing portion having a stop opening extending therethrough, and a longtiduinally extending slot that is configured to slidably receive a portion of a spinal cord stimulation lead;
• and
• a second housing portion having a stop element received in the stop opening and moveable within the stop opening, and a plurality of connector contacts positioned to electrically contact a plurality of connection contacts of the lead, and a plurality of snap-fit latches to securely carry a surface having the second connector contacts,
• wherein the first and second housing portions are pivotably connected to each other to move between a partially-opened position, in which the stop element is in a first location within the stop opening, and a closed position in which the stop element is in a second location within the stop opening.

A connector for an electrical cable in a spinal cord stimulation system, the connector comprising:

• a first housing having an elongated stop opening extending therethrough;
• and
• a second housing having
• a stop element received in the elongated stop opening and moveable within the stop opening,
• a plurality of connector contacts positioned to electrically contact connection contacts of a lead, and
• a plurality of snap-fit latches positioned to secure a support member carrying the connector contacts;
• wherein the first and second housings are movable relative to each other between a partially-opened position, in which the stop element is in a first location within the elongated stop opening, and a closed position in which the stop element is in a second location within the elongated stop opening.
