Abstract: A plug-in connection comprising a connector (1) for fitting onto a counter connector (2), contact elements (3) of the connector (1) entering into an electrical conducting connection with counter contact elements (4) of the counter connector (2), with a sleeve (7) which surrounds the contact elements (3) carried by a core (K) and forms a snap collar (18) for gripping behind a latching bead (27, 28) of the counter connector (2) and with a locking coupling (5) which is displaceable in the plugging direction and which, in a release position, allows radial escape of the snap collar (18) and, in a locking position, prevents it, the core (K) being made of a harder plastic than a casing (17) surrounding the core (K) with a spacing and forming a sleeve portion (7) which has peripheral interruptions (8 and 9) and on the inside of which the snap collar (18) of softer plastic is formed integrally with the casing (17).
