The locking member 1242 can lock the flexible flat cable 2 in the accommodating space SP. In the present embodiment, the locking member 1242 is broken from the second body 124 and suspended on the second body 124. The fastener 1242 further includes an action portion 12422, a hook arm 12424 and a hook portion 12426. The action portion 12422 is connected to the urging portion 1244. The hook arm 12426 connects the hook portion 12426 with the action portion 12422. Fig. 5a to 5b are schematic views illustrating an implementation of the ultra-thin easy-to-lock and easy-to-unlock connector of the present invention. Fig. 5a is a schematic connection diagram illustrating the ultra-thin easy-to-lock easy-to-unlock connector of fig. 1 according to the present invention connecting the flexible flat cable, and fig. 5B is a sectional view of B-B' illustrating the ultra-thin easy-to-lock easy-to-unlock connector of fig. 5a according to the present invention connecting the flexible flat cable. After the flexible flat cable 2 is inserted into the accommodating space SP, the hook portion 12426 is pushed by the flexible flat cable 2 to be lifted until the hook portion 12426 falls into the card slot 22 (see fig. 5 a) of the flexible flat cable 2, so that the hook portion 12426 interferes with the card slot 22 and the flexible flat cable 2 cannot exit from the accommodating space SP; on the contrary, after the force application portion 1244 is pressed by the external force F, the force application portion 1244 drives the action portion 12422, and the action portion 12422 lifts the hook portion 12426 through the hook arm 12424, so that the hook portion 12426 moves toward the direction of separating from the accommodating space SP, thereby achieving the purpose of unlocking the hook portion 12426 separating from the card slot 22. It is noted that there is a height difference between the action portion 12422 and the hook arm 12424, and in another embodiment, an inclined surface is formed between the action portion 12422 and the hook arm 12424 to correspond to the groove 146 of the insulator 14. The inclined surface is disposed corresponding to the recess 146 for accommodating the deformation of the acting portion 12422 and the hook arm 12424.

The force application part 1244 is disposed adjacent to the locking part 1242, and the force application part 1242 drives the locking part 1242 by the external force F to make the locking part 1242 unlock the flexible flat cable 2.
