An airbag module has a case-like housing and an open side covered by a protective covering. The protective covering (17), having a pre-set tear line, is fastened at its one end (18) in the interior of the housing (10). With its other, free end (19), the protective covering overlaps the open side (13) of the housing (10) and is secured on a flange (14) outwardly protruding from the housing wall (12) and mounted on the housing (10). The flange (14) has at least one opening (20), immediately adjoining the transition between housing wall (12) and flange (14), for guiding a tongue (22) formed on the free end (19) of the protective covering (17). A holding nose (21) projecting from the housing wall (12) into the opening (20) can be brought into engagement into a holding recess (23) formed in the tongue (22) of the protective covering (17).
