A bi-fold locking clasp, comprising:
- an assembly comprising a retractable spring-loaded slider located on a bottom side of the assembly, the slider comprising at least one locking flange;
- a short leaf rotatably connected to the assembly via a first hinge, wherein the first hinge is located on the bottom side of the assembly;
- a long leaf rotatably connected to the short leaf via a second hinge, wherein the long leaf comprises a hook configured to removably attach to the first hinge when the bi-fold locking clasp is in a closed position;
- and
- a safety latch rotatably connected to the second hinge, wherein the safety latch is configured to rotate down on top of and removably attach to the assembly when the hook is removably attached to the first hinge, and wherein the safety latch inhibits the hook being detached from the first hinge when the safety latch is removably attached to the assembly;
- wherein the at least one locking flange is configured to rest on top of a latching surface of the safety latch when the safety latch is removably attached to the assembly, and wherein the at least one locking flange inhibits the safety latch from being detached from the assembly unless the retractable spring-loaded slider is retracted.
