         6 . The buckle clip of  claim 5 , wherein the lever hole is rectangular, and the lock spring member is made by bending a flat spring plate, wherein the round projection is made by curling the spring plate at the engaging end of the lock spring member.  
     
     
         7 . The buckle clip of  claim 4 , wherein the first bracket has a flat bracket body, and a hinge on which the lever is pivotally supported, wherein the hinge is provided on the bracket body, and wherein the lever is substantially parallel with the bracket body in the fastened state, and makes a predetermined angle with the bracket body in the released state.  
     
     
         8 . The buckle clip of  claim 7 , wherein the engaging end has a round projection, wherein when the lever is pivoted to the fastened state, the lever hole slides on the round projection overcoming the force exerted by the body portion of the lock spring member, and wherein in order to pivot the lever from the fastened state to the released state, a force greater than a predetermined threshold is needed to make the lever hole slide on the round projection, whereby the buckle clip is secured in the fastened state.  
     
     
         9 . The buckle clip of  claim 8 , wherein the lever hole is rectangular, and the lock spring member is made by bending a flat spring plate, wherein the round projection is made by curling the spring plate at the engaging end of the lock spring member.  
     
     
         10 . The buckle clip of  claim 7 , the first bracket further comprises a cam spring member, wherein the cam spring member is attached to the bracket body of the first bracket in cantilever fashion, wherein the first end of the lever acts as a cam against the cam spring member so that the lever is snapped into either a state in which the lever is substantially parallel with the bracket body, or a state in which the lever makes the predetermined angle with the bracket body.  
     
     
         11 . The buckle clip of  claim 10 , wherein the engaging end has a round projection, wherein when the lever is pivoted to the fastened state, the lever hole slides on the round projection overcoming the force exerted by the body portion of the lock spring member, and wherein in order to pivot the lever from the fastened state to the released state, a force greater than a predetermined threshold is needed to make the lever hole slide on the round projection, whereby the buckle clip is secured in the fastened state.  
     
     
         12 . The buckle clip of  claim 11 , wherein the lever hole is rectangular, and the lock spring member is made by bending a flat spring plate, wherein the round projection is made by curling the spring plate at the engaging end of the lock spring member.  
     
     
         13 . The buckle clip of  claim 10 , wherein the cam spring member and the lock spring member are integrated into a single member.  
     
     
         14 . The buckle clip of  claim 13 , wherein the engaging end has a round projection, wherein when the lever is pivoted to the fastened state, the lever hole slides on the round projection overcoming the force exerted by the body portion of the lock spring member, and wherein in order to pivot the lever from the fastened state to the released state, a force greater than a predetermined threshold is needed to make the lever hole slide on the round projection, whereby the buckle clip is secured in the fastened state.
