A gas bag module ( 10 ) includes a gas bag ( 56 ) having a front wall, a center section ( 58 ) of the front wall being fastened to the gas bag module ( 10 ) and being prevented from a free movement on an unfolding of the gas bag ( 56 ). The gas bag module ( 10 ) further includes a diffusor ( 22 ) having a first diffusor element ( 24 ) fixed to the module, and a second diffusor element ( 26 ) displaceable with respect to the first diffusor element ( 24 ) by a predetermined limited displacement path (d) in an axial direction (A). The gas bag module further comprises a gas generator ( 16 ) arranged below the diffusor ( 22 ) and a covering cap ( 42 ) having a central section ( 50 ) which is fastened by at least one fastening means to the second diffusor element ( 26; 326; 326 '). The diffusor elements ( 24, 26 ) are constructed so that the second diffusor element ( 26 ) is not displaceable in a peripheral direction (U) relative to the first diffusor element ( 24 ).
