Plug-in connector comprising a secondary locking mechanism impinged by a spring

abababababThe invention relates to a plug-in connector, in particular for airbag retaining systems, comprising a first housing, which can be locked into a mating connector by means of locking arms and a secondary locking mechanism that can be impinged by a spring force. Said secondary locking mechanism has tongues, which block the locking arms once the latter have engaged in the mating connector, in addition to detent arms, which are blocked by the introduction of one edge of the mating connector until the locking arms are engaged and which then slide off the edge as a result of the spring force that has accumulated up to this point, pressing the secondary locking mechanism into its final position.
