Abstract: An improved attachment device to adjustably secure looped cable ends of a compound archery bow, either steel cables or synthetic fiber cables, to the tips of the bow limbs. The device comprising a base element, two parallel walls attached to the top surface of the base element defining a slot therebetween, each wall having an aligned aperture to receive a limb tip axle to secure the device to the limb tips, a cable support element received within the slot and slidable therewithin and adapted to receive the looped ends of the cables, a threaded bore through said base element from the top surface to the bottom surface to receive a threaded adjusting member which can be adjusted upward from the top surface of said base element to bear against a lower surface of said cable support element. The adjusting member used to adjust the distance between the cable support element and the axle mounting aperture and adjust the effective length of the bow cable.
