Abstract: The invention relates to an electrical plug connector comprising at least one plug connector housing and at least one insulation displacement contact element that can be plugged into the plug connector housing and comprises a sheet-metal stamping, which element has a contact baseplate, on which, on mutually opposite edges, a first contact plate and a second contact plate are integrally formed in one piece in a manner such that they are bent away in the same direction via a respective bending zone, the contact plates each having an insulation displacement contact device for a conductor wire, and contact-making elements for forming a contact-making device for making releasably pluggable contact with a mating plug contact element being provided on the insulation displacement contact element, in which case at least one contact plate is embodied as a contact arm in which the insulation displacement contact device is accommodated at its bending zone end region and whose free end has at least one element of the cont
