A connector assembly for gas appliances is disclosed. The connector assembly may be used in pairs and the composite hose may be fluidly connected therebetween. It may include two rotating direction. That is, the first screw pipe may rotate relative to the first pipe portion of the connecting pipe in the first rotating direction, and the second screw pipe may rotate relative to the second pipe portion of the connecting pipe in the second rotating direction which is different from the first rotating direction. It is easy to move the gas appliance relative to the gas supply and then prevents from gas leakage which results from the composite hose being twisted many times.
