Abstract
A pair of generally parallel spaced plastic arms are pivoted to each other at their central portions by interleaved pairs of tabs having a pivot pin extending therethrough. A light coil spring on the pivot pin biases one pair of opposite ends of the arms into light engagement for clipping them on to an ear lobe. The one pair of opposite ends have a pair of hollow bosses formed thereon, with heart beat sensors positioned in each boss. Electric wires connected to the sensors extend therefrom along the arms through channels formed in the arms. The pivot pin has heads formed at its opposite ends. Apertures are formed in these heads and an elongated strip of plastic material has its opposite ends positioned in the apertures so that the remainder of the strip of material comprises an open loop for hanging the arms off the ear of the lobe to which the arms are clipped. The strip of material has a friction fit in the apertures so the size of the loop can be adjusted by selectively pulling the ends of the strip through the apertures.
