A tether clip (100, 200) for interconnecting an anchor structure and an accessory, comprising: an upper clamping member (102, 202) having an upper contact area (106, 206) positioned between an upper clamping end (103, 203) and a lower lanyard receiving end (116, 216); a lower clamping member (132, 232) having a lower contact area (136, 236) positioned between a lower clamping end (133, 233) and an upper lanyard receiving end (146, 246), the lower clamping member being pivotally connected to the upper clamping member; a biasing member (151, 251) interconnecting the upper clamping member and the lower clamping member and biasing the upper clamping member and the lower clamping member in a closed position; wherein the lower lanyard receiving end and the upper lanyard receiving end are adapted to receive a lanyard (154, 254) connected to the accessory; wherein the tether clip is configured and arranged such that pressure exerted on the upper contact area and the lower contact area overcomes the biasing member to move the upper clamping member and the lower clamping member in an open position for receiving the anchor structure between the upper clamping end and the lower clamping end; such that when pressure is removed from at least one of the contact areas, the biasing force from the biasing member moves the tether clip back into the closed position, so that the anchor structure received between the upper clamping end and the lower clamping end is positioned between said clamping ends in the closed position; and such that 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. an upper clamping member (102, 202) having an upper contact area (106, 206) positioned between an upper clamping end (103, 203) and a lower lanyard receiving end (116, 216); a lower clamping member (132, 232) having a lower contact area (136, 236) positioned between a lower clamping end (133, 233) and an upper lanyard receiving end (146, 246), the lower clamping member being pivotally connected to the upper clamping member; a biasing member (151, 251) interconnecting the upper clamping member and the lower clamping member and biasing the upper clamping member and the lower clamping member in a closed position; wherein the lower lanyard receiving end and the upper lanyard receiving end are adapted to receive a lanyard (154, 254) connected to the accessory; wherein the tether clip is configured and arranged such that pressure exerted on the upper contact area and the lower contact area overcomes the biasing member to move the upper clamping member and the lower clamping member in an open position for receiving the anchor structure between the upper clamping end and the lower clamping end; such that when pressure is removed from at least one of the contact areas, the biasing force from the biasing member moves the tether clip back into the closed position, so that the anchor structure received between the upper clamping end and the lower clamping end is positioned between said clamping ends in the closed position; and such that 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.
