An airbag module has an inflator activated via an electrical connector. The inflator includes an initiation assembly having an initiator and a receptacle that retains the connector. The initiator may have a single, center pin. The initiator may be encased by a body and cover, which may be attached together by molding, vibratory welding, electromagnetic welding, or snap fitting. The connector may have projections that extend from a main body to facilitate retention of the connector by a collar, washer, a retainer attached to the body, or by the inflator housing. The body may be seated in a collar having an annular ridge that presses into the body to form a seal. The connector may have a rib designed to mesh with splines of the receptacle to enable engagement of the connector with the receptacle in multiple orientations, while preventing relative rotation between the connector and the initiator after assembly.
