A plug connector assembly comprising a plug-side connector and a socket-side plug connector;

• wherein
• the plug-side connector comprises a first housing within which at least two electrical contact elements, each comprising a plastic tip formed at one end of a contact region, are arranged next to one another, in parallel, and extend along an insertion direction within an opening of the first housing;
• the first housing further comprises a pivotable protective flap, including at least one protective flap locking hook, which covers the opening of the first housing;
• and
• at least one dome-like shock hazard protection body within the first housing, extends adjacent the contact elements in the insertion direction;
• and
• at least one latching lug is provided on either the first housing or a wall bushing for the first housing;
• and
• the socket-side plug connector comprises a second housing that includes at least one socket locking hook;
• such that,
• when the protective flap covers the opening of the first housing, the protective flap locking hook releasably engages with the latching lug;
• and
• when the protective flap is pivoted to reveal the opening of the first housing, the socket locking hook, of the socket-side plug connector, releasably engages the latching lug upon mating with the plug-side connector along the insertion direction.
