PLUG CONNECTOR

A plug connector having a first connector and a second connector, connected by a joining movement along an axis of main extent of the plug connector, wherein a securing element associated with the first connector can be shifted between a locking position (A) and an unlocking position (B) along the axis of main extent, a fixing element can be deflected in the radial direction (III), and wherein the fixing element can be released by a movement in the radial direction (III) by shifting the securing element out of the locking position (A) to the unlocking position (B). In the locking position (A), the securing element is designed so as to permit the fixing element to move in the radial direction (III) in order to allow a joining movement in the axial direction (I) for connecting the first connector to the second connector.
