The connector shroud of the present invention includes an inner housing, a coupling nut and a lock nut. The inner housing is hollow and a grooved control link is formed on the outer surface of the inner housing. The grooved control link extends in a longitudinal direction. The coupling nut is hollow and is sleeved onto the inner housing. A receiving recess is formed on the inner surface of the front end of the coupling nut for accommodating a protrusion provided on a flange. A tab protrudes from the rear end of the coupling nut. A control slot is formed on the tab and includes a first section and a second section. The second section communicates with the first section and extends in a direction not parallel to the longitudinal direction. The lock nut is hollow and sleeved onto the inner housing. A first pin and a second pin are formed on the inner surface of the lock nut. The first pin is disposed in the grooved control link. The second pin is located in the second section, wherein the movement of the lock nut causes the coupling nut to rotate.
