The cam engaging part (6) projecting to one side of the fixing case (3) is provided to move retractably toward the inside of the fixing case (3), together with the cam part (4), while resisting against the urging spring (5) such that it can be secured, with one touch, to the second member (2) through the retracting motion and the reset motion of the urging spring (5).</p> |
