ABSTRACT OF THE DISCLOSURE An article clamp, particularly useful as an electrode clip, is pro- vided herein which is formed of resilient plastic material, e.g. polypropylene. The clamp includes an open bottomed box-like enclosure including opposed side walls, frontal and distal end connecting portions, e.g., as spaced apart front and rear partial top walls, and preferably also integral with opposed end walls and preferably also a pair of supporting flanges extending outwardly from an open bottom. A primary electrical contact plate, e.g., of a channel-shape and having an access slot therein is disposed across a portion of the open bottom. The electrical contact plate has means to enable connection to an electrical lead wire, e.g., in the form of an upward extension thereof. The clamp also in- cludes an articulable cover which is integral with the box-like enclosure. The cover includes a first swingable member secured to a frontal connecting end of the box-like enclosure by means of a first living hinge. The first swingable member has a second cooperating electrical contact plate secured thereto. A second swingable member is secured at one end thereof to the free end of the first swingable member by means of a second living hinge. A third swingable member is secured at one end thereof to the free end of the second swingable member by a third living hinge, and to a distal wall of the box-like enclosure by a fourth living hinge. An operating lever is integrally secured to the third swingable member. In operation, when the primary electrical contact plate is disposed in electrical contact with the stud of the male electrode, and when the operating lever is urged downwardly toward the primary electrical contact plate, the first swingable member is urged downwardly to place the second co- operating electrical contact plate into electrical contact with the stud of the male electrode. The third living hinge is moved to a positive over-toggle posi- tion to lock the contact plates and the male electrode stud in engagement with one another. This electrode clip can be easily manipulated with one hand to secure the connector to the electrode stud, e.g. one temporarily attached to a human body, to a lead cable of an electrocardiograph, without any signifi- cant amount of pressure being applied directly downwardly to the stud and hence to the human body.
