A vehicle steering wheel assembly (20) includes an air bag module (24) connected with a frame (42) of a vehicle steering wheel (22). The module (24) includes an inflator (62), an air bag (64), and a mounting hub (66). An internal groove (184) in the mounting hub (66) receives resiliently deflectable tabs (208) on the inflator (62) to secure the inflator to the mounting hub. A mounting portion (240) of the air bag (64) is received in one section of an external groove (182) on the mounting hub (66). A base portion (262) of a guide ring (260) is received in another section of the external groove (182). A wall portion (266) of the guide ring retains the mounting portion (240) of the air bag (64) in the groove, to secure the air bag to the mounting hub. The steering wheel frame (42) has a plurality of tabs (164) which are deformed into slots (162) in the mounting hub to secure the module (24) to the frame. A single fastener (40) secures the mounting hub (66) and thereby the module (24) to the vehicle steering shaft (26).
