According to this patent application, a tension release device is designed to separate when a predetermined tension has been exceeded. A resilient tube has longitudinal slots formed in it to create a plurality of resilient prongs. Projections on the prongs form a radially projecting, broken annular rim. A plug shaped insert or a cup shaped element, depending on whether or not the broken annular rim projects radially inwardly or radially outwardly, is disposed with its tapered camming surface coaxially aligned with the broken annular rim. As the predetermined tension is exceeded, the projections are cammed out of the axial path of the camming surface and the device releases. Optionally, a third member is coaxially carried adjacent the resilient tube to vary the force necessary for separation.
