An electrical connector part for connecting to a mating electrical connector part, comprising:

• a housing that has an insertion portion configured to make a plug-in connection with the mating electrical connector part, and a locking element, arranged moveably on the housing, which is configured to lock the mating electrical connector part to the housing in a locked position, and which is movable out of the locked position in order to release the locking connection between the mating electrical connector part and the housing when in an unlocked position;
• and
• a connecting device that connects the locking element to the housing and has a guide portion, a guide element guided at the guide portion, and a spring element, the spring element having a locking leg configured to latch the guide element to the guide portion in the locked position and/or the unlocked position,
• wherein the guide element is configured to slide along the locking leg when the locking element is moved between the locked position and the unlocked position, and
