Proposed is an apparatus for coupling an airbag module to a steering wheel. A coupling open area extends completely through a steering wheel in a forward-backward direction. A hook extends from a rear portion of an airbag module to behind the steering wheel, and includes a bent portion provided on a distal end to be bent in a direction intersecting a longitudinal direction of the hook. A fixing clip is disposed on a rear portion of the steering wheel and fixed to the steering wheel, with an end of the fixing clip being caught by and coupled to the bent portion of the hook to stop movement of the hook forward of the steering wheel. A catching protrusion protrudes from the rear portion of the steering wheel to catch the end of the fixing clip and stop movement of the fixing clip when the hook is decoupled.
