Abstract: The cable locking system is a two-part device that locks a cable-like strap or other flexible or rigid member with an enlarged end into place by using an opposing arrangement of keyhole-shaped apertures bored into two rigid parts. The cable locking system requires no extra hardware to secure the connection, and can be retrofitted to fit virtually any size support system in numerous applications. The cable locking system can be installed quickly and easily without a need for tools, extra labor, or supporting equipment. In the case of a suspension bridge, the suspension parts can be pre-manufactured and assembled, then quickly and easily connected to complete the structure. The cable locking system makes the construction of a suspension bridge or other hoisting device as well as many kinds of structures simple and straightforward, with fewer parts that can potentially fail. The cable locking system can also easily be disassembled.
