Disclosed is a device for assembling and disassembling a gas rifle and a gas tank to and from each other, respectively. The device comprises a gas tank having a rear cap which has an adjusting valve for adjusting a gas discharging amount and a one-touch type connection pipe which has an inclined surface at a distal end thereof and a circumferential bearing groove; a gas discharging pipe; a fixed pipe having a plurality of holes and a plurality of balls which are fitted into the plurality of holes, respectively, the plurality of balls being able to be moved between a retracted position and a projected position, being engaged into the circumferential bearing groove at the retracted position and being disengaged from the circumferential bearing groove at the projected position; a control pipe for controlling the movement of the balls between the retracted position and the projected position, thereby to allow the gas tank to be assembled to the gas discharging pipe when the balls are in the retracted position and disassembled from the gas discharging pipe when the balls are in the projected position; and a contact valve being brought into close contact with the inclined surface when the gas tank is assembled to the gas discharging pipe and being detached from the inclined surface when the gas tank is disassembled from the gas discharging pipe.
