Abstract: A device for a door hinge structure of the snap-in type, where the hinge has a first hinge flap designed to be secured to a door frame and pivotally attached to a second hinge flap in the form of an insertion part which can be snapped into an insertion pocket in a receiving part that is secured to an end portion of a door leaf. The receiving part has a spring-loaded peg which is slidably mounted in a slide that is moveable parallel to the depth direction of the insertion pocket. The slide forms steplessly adjustable threaded engagement with an axially immoveable, rotatable adjusting screw, provided in the receiving part, and the peg is moveable transverse to the insertion pocket for releasable engagement with a hole or a cut-out portion in the insertion part, whereby the length of insertion of the insertion part in the depth direction of the insertion pocket is steplessly adjustable.
