Abstract: An elongated tether member is provided including a main elongated flexible tubular body having anchor sleeves carried by its opposite ends. One of the anchor sleeves supports anchor structure therefrom including at least one movable component shiftable between operative anchoring and inoperative release positions and an operator is shiftably supported from the other sleeve for movement between active and inactive positions. Motion transmitting structure is disposed within the tubular body establishing at least a one-way motion transmitting connection between the operator and the movable component functional to shift the movable component from the operative position to the inoperative position thereof responsive to the movement of the operator from the inactive position to the active position. An outer flexible tubular housing is disposed about the tubular member and includes opposite ends anchored relative to the sleeves.
