[Means for Solving the Problems]

 The present invention is a separate type including a half metal fitting having a pivoting portion at the front end of a base member for rotatably mounting an opening / closing plate and another half metal fitting having a hanging shaft for hanging on the metal fitting at the front portion. In the clasp, a hooking member that has an operating protrusion on the upper surface of the base member of the one-half metal fitting and is slidable forward and backward or left and right when biased is provided, and the hooking member is attached to the front end of the opening and closing plate. A locking groove is provided on the locking projection of the locking member, and a tension spring for flipping up the opening / closing plate when the locking groove is released is provided in the rotating portion of the opening / closing plate. It is an attempt to solve a problem.

[0005]

[Action]

 When the opening and closing plate of the first half fitting that has been deployed on the hanging shaft at the tip of the other half fitting is passed through and then the opening and closing plate is closed, the lower part of the locking groove at the tip of the opening and closing plate is the end of the locking projection of the locking member. When the latch groove exceeds the end of the latching protrusion while sliding the latching member in the backward or left-right direction by pressing, the latching member returns to its original position by the biasing force, and the latching protrusion occurs. Is engaged with the retaining groove to engage the opening / closing plate, and thereby connects the clasp. To release the connection, push the operating knob on the top with your fingers and slide the latching member to unlock the latching protrusion and the latching groove, and the tension spring causes the opening / closing plate to spring up and open. It will be possible to separate it by removing it from the hanging shaft of the other half bracket.
