1. A system for securing an object to a substrate having an eyelet comprising:
an elongate cable having an outer diameter and with a fixed loop having an interior diameter with the loop created by a splice or swage having an outer diameter at a first end of the cable and a fist also having an outer diameter at a second end of the cable with the fist outer diameter larger than the cable outer diameter, but smaller than the splice or swage outer diameter,
a hollow cylindrical lock body having an exterior diameter and a first portion with a first interior diameter and a second portion with a second interior diameter with the first interior diameter larger than the second interior diameter and a shoulder separating the two interior diameters, the lock body first portion also having a pair of opposed transverse apertures or notches having a first diameter larger than the fist outer diameter, but smaller than the splice or swage outer diameter;
a fixed cap having an exterior diameter and a first end enclosing the end of the first portion of the lock body and a second end proximate the lock body apertures or notches, the cap also having an aperture with the elongate cable slidingly extending through the aperture, with the cap aperture having an axis normal to the axis of the lock body and the cap aperture having a smaller diameter than the lock body apertures, the swage or splice outer diameter and the fist outer diameter, but larger than the cable diameter;
a barrel configured to have limited longitudinal movement in the lock body, the barrel having interior splines configured to accept tumblers, the barrel also having a first face adjacent the pair of lock body apertures or notches and opposite the cap second end;
a barrel spring adapted to bias the barrel away from the cap;
a plug having a keyway and radially extending tumblers, the plug configured to move longitudinally with the barrel and rotate inside the barrel when the tumblers are retracted from the splines by an appropriate key inserted into the keyway, the plug also having a cam that provides motion normal to the longitudinal axis of the lock body when the plug is rotated; and
a bolt in the interior of the lock body biased by a bolt spring to move radially outwardly to contact the shoulder in a first locked state wherein the cap second end and the barrel first face are located at a distance less than the first diameter of the pair of transverse apertures or notches, and configured to be moved by the cam against the bias of the bolt spring to retract the bolt away from the shoulder in an unlocked state, and the barrel spring biases the barrel first face longitudinally away from the cap second end to a distance equal to or larger than the first diameter of the pair of transverse apertures or notches;
and wherein the cable passes through the eyelet in the substrate, the cable, the body and the cap pass through the interior of the cable fixed loop and the cable passes through the object to be secured and the cable and fist pass through the pair of lock body apertures and between the barrel first face and cap second end when the lock is in the unlocked state but the fist will not pass between the barrel first face and cap second end when the lock is in the locked state.
