The plow apparatus for laying underground cable includes a heavy plow blade having a laterally slotted metal tube permanently affixed to its trailing edge. The slot allows a wire, cable, etc. to be placed in the tube without need to cut the cable for insertion into the tube from one end thereof. A sleeve is removably installed within the tube, and may have an elongate slot therein. The slotted sleeve is first placed around the cable, and then slid into the tube of the plow blade. The sleeve is rotated to misalign its slot relative to the slot of the blade tube, thereby capturing the cable within the tube and sleeve. The process is reversed for cable removal, thus allowing the cable to be installed in or removed from the tube and blade without cutting the cable. The sleeve may be circumferentially closed, i.e., unslotted, if desired.
