A plug connector for electrically connecting a tag connector to an electrical line of a motor-driven garden and/or forestry working apparatus includes a tag connector receptacle portion and a line receptacle portion. The tag connector receptacle portion has a first surface-clamping leg, a second surface-clamping leg, a first peripheral guiding blade and a second peripheral guiding blade, wherein the surface-clamping legs are disposed so as to be opposite one another and wherein the peripheral guiding blades are disposed so as to be opposite one another. The tag connector receptacle portion is configured for elastically enlarging a leg spacing between the surface-clamping legs and for plastically enlarging a blade spacing between the peripheral guiding blades by interaction between the peripheral guiding blades and the tag connector for receiving the tag connector and for contacting and for impinging with a clamping force opposite surfaces of the received tag connector by the surface-clamping legs, and for contacting opposite peripheries of the received tag connector by the peripheral guiding blades for securing the received tag connector against being released from the tag connector receptacle portion and for electrical contacting. The line receptacle portion is electrically connected to the tag connector receptacle portion. The line receptacle portion is configured for receiving the electrical line and for securing the received line against being released from the line receptacle portion and for electrical contacting.
