Abstract: A terminal for detachably connecting an electrical lead to an electrical device is disclosed. The terminal includes a stationary support structure adapted to be fixed to the device, and a movable structure adapted to be carried by the stationary support structure for movement between first and second positions relative to the support structure. The movable structure has a plurality of wall members thereon that are movable relatively toward and away from one another between a first spaced apart position less than the diameter of the electrical lead and a second spaced apart position greater than the diameter of the electrical lead for receiving and releasing the lead in the second spaced apart position and for gripping the lead in the first spaced apart position.
