ABSTRACT:
A connector for electrodes in the form of an electrode clip is provided herein which is formed of resilient plastic material, e.g., polypropylene. It includes a fixed jaw and a movable jaw, the jaws being provided with cooperating female electrical contacts. An operating mechanism is provided which is composed of a plurality of elements interconnected together by at least two living hinges, one of which being secured to the movable such jaw, and the other interconnecting two operating members but preferably having at least three living hinges, one of the living hinges being integrally secured to the movable such jaw, with the other two living hinges interconnecting three operating members. The operating mechanism includes an operating lever which is movable to urge one jaw towards the other jaw, and thus to urge the jaws into a closed position. This action simultaneously forces a preselected one of the living hinges to an over-toggle position to lock the jaws in such closed position. This electrode clip can be easily manipulated with one hand to secure the connector to the electrode stud which is disposed, e.g., on a human body, to a lead cable, e.g., of an electrocardiograph, without any pressure being applied directly to the stud and hence transmitted to the human body.
