PURPOSE: A clamping device reduces the space needed for installation thereof and makes the standardization thereof by using a fire hose expanding on air injection. CONSTITUTION: The clamping device comprises a lower gun(16), an upper gun(14), a fire hose(18) and an elastic member(20). The lower gun(16) has a lower clamping part(28) placing a material(12) to be clamped. The upper gun(14) has an upper clamping part(26) hingedly connected with the lower gun(16) and hingedly moving to push the material(12) to be clamped. The fire hose(18) is interposed between the lower gun(16) and the upper gun(14) and expands when pneumatic pressure is inputted to make the upper clamping part(26) of the upper gun(14) and the lower clamping part(28) of the lower gun(16) clamp the material(12). The elastic member(20) connects the end of the lower gun(16) with the end of the upper gun(14) to elastically support the upper gun(14) and the lower gun(16) to return to the original position when the pneumatic pressure disappears.
