PURPOSE:To provide a buckle, which consists of a buckle main body and an insertion, and the structure of the buckle is simple, and even if a load is applied thereto in any state, engagement between them is not released, and if operation of separating is done only once, the engagement can be simply and surely released and separated. CONSTITUTION:For a buckle main body 1, an upper plate 5 and a lower plate 6 are joined each other at one end thereof. On the upper plate 5, a circular through-hole part 9 is formed, and on the lower plate 6, a locking plate 12 which is joined at the side of an opening to be inserted on a circular edge part 10, and a locking part 11 formed at the top end thereof, is formed in the state of being deformedly bent inwardly. For an insertion 2, an operating plate 15, which is joined at the side of a basic part 14 on an inserting plate 13 by providing a downward projection part 16 formed at the top end thereof and is always elastically brought into contact with the locking plate 12, is flexibly formed, and an engagement part 18 engaged with the locking part 11 is formed on the rear at the circular periphery part 17 of the inserting part 13. Engagement between them is released by pushing the operating plate 15. |
