A positive lock for components of an air bag inflator assembly that includes a first member having a recess formed therein and comprising an ignition tube, a second member comprising a retainer disk, and a retaining means for locking the ignition tube to the retainer disk. The retainer disk has a hollow collar portion with a plurality of indented features formed in the distal end of the collar. At least a portion of the indented features are disposed in the recess in the ignition tube, thereby locking the retainer disk to the ignition tube. The indented features are configured such that upon a force parallel to the longitudinal axis of the ignition tube acting upon the retainer disk, the indented features deform so as to be at least partially disposed in the recess formed in the ignition tube. An inflator assembly for generating gas to rapidly inflate an air bag is also provided that includes a housing defining an interior space therein, an inner side wall with a recess formed therein, and a retainer disk The housing has a top wall, a lower portion, and an outer side wall. The inner side wall comprises an ignition tube that is connected to the lower portion of the housing and has ignition ports formed therein. Ignition tube defines an ignition chamber therein for containing an igniter and a combustion chamber between the inner side wall and the outer side wall for containing a gas generating material. A filter is disposed in the combustion chamber proximate to the interior surface of the outer side wall. The retainer disk is disposed over the inner side wall proximate to the top wall of the housing and has a collar portion that is configured to cooperate with the ignition tube. The collar has indented features formed therein that are at least partially disposed in the recess in the ignition tube, thereby positively locking said retainer disk to said ignition tube.
