The utility model relates to a novel hanging buckle, which belongs to the technical field of connecting buckles and comprises a male buckle seat and a female buckle seat, a buckle head is arranged on the front side of the male buckle seat, a counter bore and a central hole are arranged on the front side of the buckle head, a spring bead is arranged in the central hole, the edge of the buckle head extends outwards to form a U-shaped outer edge, and strip-shaped grooves are arranged on the back sides of two parallel edges of the U-shaped outer edge. One end of the strip-shaped groove is communicated, the other end of the strip-shaped groove and the U-shaped outer edge form a first step surface, a shell is arranged on the front face of the female buckle seat, a notch is formed in one side wall of the shell, a U-shaped groove is formed in the front face shell wall of the shell, and a second step surface is arranged on the inner side, close to the edge of the U-shaped groove, of the front face shell wall of the shell. The spring bead is pressed to contract and store energy, the male buckle base is loosened after alignment, the spring bead releases energy to enable the male buckle base and the female buckle base to generate axial repulsion, then the first step face on the buckle head and the second step face on the shell abut against each other and are buckled, the self-locking effect is achieved, and the hanging buckle is prevented from being unclamped accidentally.
