  • Patent number: 11143220
    Abstract: A tether clip for interconnecting an anchor structure and an accessory comprises an upper clamping member, a lower clamping member, and a biasing member. The lower clamping member is pivotally connected to the upper clamping member, and the biasing member biases the upper clamping member and the lower clamping member in a closed position. A lower lanyard receiving end and an upper lanyard receiving end are adapted to receive a lanyard connected to the accessory. When the lanyard is under a tensile load, a lateral force is exerted on the lower lanyard receiving end and the upper lanyard receiving end, which translates to a torsional load on the upper clamping end and the lower clamping end to place a stronger clamping force on the anchor structure in the closed position.
