  • Patent number: 11766097
    Abstract: A buckle may include male and female parts. In a case (A) where only the female part is attached to a slider of a slide fastener, the male part includes: a pair of arms respectively provided with locking protrusions; and a connecting rod connecting respective base ends of the pair of arms. The connecting rod is configured to curve away from a space between the locking protrusions of the arms when the arms are bent such that the locking protrusions approach one another. In a case (B) where the male part is attached to a slider of a slide fastener, the male part includes: a slider-holding frame configured to hold the slider; and a pair of arms that extend in the same direction from the slider-holding frame and are respectively provided with locking protrusions. The slider-holding frame includes a frame portion protruded into a space between the pair of arms toward a space between the locking protrusions.
