Abstract: The present application relates to a detachable plug-in connector, which includes an insertion tube having a lock engaging portion, a receiving part for accommodating the insertion tube, and a self-locking member for limiting the movement of the insertion tube. The self-locking member is accommodated in the receiving part. The self-locking member comprises two limiting arms each defining a limiting protrusion, an elastic bending portion connected between the two limiting arms, and two moving portions. The receiving part comprises a limiting arm separating portion configured for cooperating with the moving portions. The moving portions are fixed at inner sides facing towards each other of the two limiting arms. The surfaces of the moving portions adjacent to the limiting arm separating portion are inclined surfaces that facilitate the two limiting arms move away from each other when the moving portions and the limiting arm separating portion squeeze against each other.
