ABSTRACT:
A shackle apparatus including a generally U-shaped shackle body having an arcuate end, a pair of parallel arms, and a retaining member spanning a gap defined between the shackle arms. The retaining member cooperates with the shackle body to define a closed loop which can be permanently attached to a sling or lifting cable. The retaining member prevents the shackle apparatus from being removed and installed on another sling or lifting cable without substantially destroying the shackle apparatus of the present invention.
