Abstract: A connector housing for an air bag connector and a method for contacting an air bag connector. A connector housing having at least two sections is provided with locking elements for a pre-lock-in position and a final lock-in position. In the pre-lock-in position, both sections of the housing are arranged apart from one another and the pre-lock-in position is localized by means of a spacer to maintain the pre-lock-in position maintain at a predetermined distance so that electric conductors can be introduced into the connector housing.
