Abstract: A locking lever is formed to include a pair of legs 16 upright from the wall of a first connector 10 and a pair of free ends 17 which continuously cross the pair of legs and provide a locking portion 18. A releasing lever 20 is formed to return to the legs from the free ends 17. A second connector 40 is provided with a hitting portion which hits against the end of the second connector 40. When the releasing lever is pushed, the free ends 17 are lifted by the theory of leverage at the furculum of the hitting portion, thereby releasing the locking between the engagement portions 18, 50. The releasing lever 20 includes a pair of arms 21 and a pressing portion 23 which continuously crosses the pair of arms. This configuration provides a connector locking structure which can prevent the base of the locking lever from being deformed and improve the feeling of clicking in coupling and capability of releasing the locking.
