Connector for a safety restraint system, for instance for an airbag ignition system, comprising: a plug connector (100; 200; 300; 110; 210; 310; 510; 610); at least two terminals (111, 112; 211, 212; 311, 312; 511; 512; 611, 612) assigned to the plug connector having corresponding signal lines (113, 114; 213, 214; 313, 314); wherein in order to allow an electrical monitoring of the correct coupling of the plug connector, the terminals (111, 112; 211, 212; 311, 312; 511; 512; 611, 612) are in electrical contact with each other in the uncoupled or incorrectly coupled condition of the plug connector, wherein the electrical contact between the terminals (111, 112; 211, 212; 311, 312; 511; 512; 611, 612) is established by at least one contact means (115, 116; 215, 216; 315, 316, 317; 501; 601) which in the uncoupled or incorrectly coupled condition of the plug connector (100; 200; 300; 110; 210; 310; 510; 610) is in a position to electrically connect the terminals with each other providing a low current flow to the terminals and which can be disconnected from the connecting position upon correct coupling of the plug-connector to a corresponding counter-connector interrupting the low current flow being detectible by means of electronic control means, wherein the contact means (315, 316, 317) is provided in form of two bendable contact tongues each tongue associated with one of the terminals and being oriented essentially in plug-in direction, whereby the two contact tongues are arranged in an x-shape orientation with respect to each other and contacting each other in the uncoupled or incorrectly coupled condition of the plug connector (300; 310), so that due to the x-shaped orientation of the tongues upon moving the free ends of the two contact tongues towards each other the two tongues are moved out of contact with each other. a plug connector (100; 200; 300; 110; 210; 310; 510; 610); at least two terminals (111, 112; 211, 212; 311, 312; 511; 512; 611, 612) assigned to the plug connector having corresponding signal lines (113, 114; 213, 214; 313, 314); wherein in order to allow an electrical monitoring of the correct coupling of the plug connector, the terminals (111, 112; 211, 212; 311, 312; 511; 512; 611, 612) are in electrical contact with each other in the uncoupled or incorrectly coupled condition of the plug connector, wherein the electrical contact between the terminals (111, 112; 211, 212; 311, 312; 511; 512; 611, 612) is established by at least one contact means (115, 116; 215, 216; 315, 316, 317; 501; 601) which in the uncoupled or incorrectly coupled condition of the plug connector (100; 200; 300; 110; 210; 310; 510; 610) is in a position to electrically connect the terminals with each other providing a low current flow to the terminals and which can be disconnected from the connecting position upon correct coupling of the plug-connector to a corresponding counter-connector interrupting the low current flow being detectible by means of electronic control means, wherein the contact means (315, 316, 317) is provided in form of two bendable contact tongues each tongue associated with one of the terminals and being oriented essentially in plug-in direction, whereby the two contact tongues are arranged in an x-shape orientation with respect to each other and contacting each other in the uncoupled or incorrectly coupled condition of the plug connector (300; 310), so that due to the x-shaped orientation of the tongues upon moving the free ends of the two contact tongues towards each other the two tongues are moved out of contact with each other.
