Abstract: The invention concerns an electrical plug connector with a housing having a housing body and a trunk projecting therefrom for receiving electrically connected contact elements for establishing contact with corresponding contact portions of an associated receptacle as well as with spring-acting catch arms on the trunk for making the housing fast in corresponding recesses of the receptacle.

Abstract: The invention concerns an electrical connector, in particular for use between a receptacle (squib) and an electrical control for a restrain system in motor vehicles.

Abstract: An electrical connector is arranged to be used with a counter plug, for example for use between a counter plug and an electrical control apparatus for an inflatable restraint system or airbag in a motor vehicle. The electrical connector includes a shell in which contacts are to be positioned and a locking member for locking the contacts in position. If the contacts are not properly positioned, the locking member cannot be pushed from a first catching position to a final catching position, and when the locking member is in the first catching position, the locking member is arranged to prevent insertion of the counter plug into the shell.

Abstract: An electrical connector is arranged to be connected to an associated element and disposed together with the associated element within a hollow body. Radially extending tongues having detents are formed on the shell of the connector, the tongues being bent at an approximately 90.degree. angle during insertion of the connector and associated element into the hollow body to retain the connector and associated element within the hollow body. The associated element may be the generator and of a vehicle airbag system, and the hollow body may be a steering column of the vehicle.
