The invention relates to a hinge for detachable sheet metal cabinet doors or walls, comprising a first hinge part or frame part that can be secured to the door or cabinet frame, and a second hinge part or door hinge part that can be fixed to the door leaf or cabinet wall, which hinge parts are connected to one another in an articulated manner by means of a hinge pin, and having a latch-type tongue that is arranged in the second hinge part such that it can move against a spring force, characterised by a lifting device which encompasses the hinge pin guided through finger-type ends of the first hinge part and which centrally supports the hinge pin together with a hook retained by the door part, such that the lifting device moves the encompassing part of the second hinge part perpendicular to the plane of the door leaf or cabinet wall, via actuation, by means of a key, such as a double bit key.
