A plug connection for jaw stump models for the releasable connection of tooth crown segments or jaw segments to a model base, which includes a plug pin ( ) which can be connected in snap-lock fashion with a sleeve ( ). A non-rotationally symmetric design of a rotational locking section ( ), and a cross pin ( ) arranged perpendicular to the plug pin axis, prevent rotary movement of the plug pin ( ) in the sleeve. Disposed at the end of the plug pin ( ) facing the sleeve is a spring element ( ), which is provided with a circumferential annular groove ( ) for a snap-locking connection with the sleeve. The spring element ( ) comprises two spring tongues ( ) separated by a continuous longitudinal slot ( ). The sleeve provided for receiving the plug pin ( ) comprises a projection projecting into the inner chamber for the snap-lock connection of the plug pin ( ) with the sleeve as well as a sleeve opening region matching the rotational locking section ( ) of the plug pin ( ).
