A plug connector part for electrically contacting a mating plug connector part includes: a contact element, which is engageable in a plug-in manner with a mating contact element of an associated mating plug connector part in an insertion direction for electrical contacting; and a lance element that includes an at least partially resilient shaft and a contacting portion, the shaft being connected to the contact element at a first end and the contacting portion being arranged at a second end of the shaft such that the contacting portion remains in electrical contact with the mating contact element of the mating plug connector part when the connector part is released from the mating plug connector part after the electrical contact between the contact element and the mating contact element has already been broken.
