Abstract: A clothes hanger clasp, particularly to a clothes hanger clasp that will not easily fall off but can be loosened in a convenient way, includes a metal plate roughly in a "U" shape, where the metal plate is divided into an upper clasp plate and a lower clasp plate that are somewhat curled inwardly. On the upper clasp plate is a protruding part and a force applying mechanism that is curled inwardly. The protruding will enable stronger elasticity to for clothes hanger clasp, and, acting with the upper and lower metal clasp plates, it will tightly clasp onto the clothes hanger. The force applying mechanism facilitates easy application of force to loosen the hanger clasp, and it is designed so that the hanger clasp will not fall off easily, but it can be loosened in a convenient way.
