A plug connector with latch means includes a casing, a mating portion and a latch means. The latch means consists of a lock member and a press member. The lock member has a lock arm, the front end of the lock arm projects sideward and defines a pawl, the back end projects sideward and defines a projection. The front end of the press member bends inward to define a press portion, the back end bends inward to define a blocking portion. To disengage the plug connector from the mating connector, the casing is pulled, the press member is driven to move backward along with the casing and the press portion presses the projection of the lock member, the projection is driven to move inward and drives the pawl move into the inlay cavity, thereby, the plug connector with latch means disengages from the mating connector easily.
