A hinge joint, particularly for a closure element such as a door, lid and the like for an opening in a container, vehicle, holding tank and the like, comprises a hinge leaf which is securable to a closure element and has a knuckle bearing, a hinge bolt, defining a hinge joint axis pivotally mounting the closure element via the knuckle bearing, a hinge bearing having a base securable adjacent to an edge of an opening, the hinge bearing having legs between which the knuckle bearing is positioned and which carries the hinge bolt, the knuckle bearing having at least one first protrusion extending axially outwardly and arranged concentrically relative to the hinge bolt, at least one of the legs having an axially inwardly extending protrusion which axially overlaps the first protrusion, the hinge leaf together with the closure element being arranged so that it can be removed from the hinge bearing only after removal of the hinge bolt and after opening the closure element through a predetermined first pivot angle, the at least one first protrusion being annular, the at least one second protrusion being formed as an enclosing retainer of an associated one of the legs and arranged radially outside of an associated one of the first protrusions, the enclosing retainer at at least one side face of the leg being provided with an access passage for the at least one first protrusion, and cam means provided on the hinge leaf, so that only in a pivoted position of the closure element corresponding to the predetermined first pivot angle there is a minimum dimension of the cam means extending perpendicular to the hinge joint axis with the hinge bolt removed, so that the passage of the at least one first protrusion through an associated one of the access passages is possible. |
