A hinge for the pivotable connection of two wall elements comprising: - a first fitment which can be arranged on a first wall element, - a second fitment which can be arranged on a second wall element, - a rotary joint which interconnects the first fitment and the second fitment pivotably about an axis of rotation, wherein the rotary joint has a pin arranged non-rotatably on the first fitment and the first fitment and the second fitment in an adjustable relative angular position with respect to each other are in a rest position from which they are pivotable by an applied force against at least one force storage means and the first fitment and the second fitment in at least one further relative angular position, preferably about +90° or -90° relative to each other, are in an arresting position in which they are releasably arrested to each other against the action of the at least one force storage means, wherein the arresting can be overcome by the application of force by an operator, - an adjusting device actuatable by means of at least one actuating means for adjusting the adjustable relative angular position, wherein the adjusting device further includes - a first part arranged non-rotatably and axially displaceably on the pin, - a second part which during actuation of the adjusting device is non-rotatable relative to the first fitment and rotatable relative to the second fitment, wherein the first part is acted upon with force by the at least one force storage means relative to the second part in such a way that upon actuation of the at least one actuating means the second part functions as a counterpart support for the at least one actuating means and the force exerted on the second part by the actuation of the at least one actuating means is transmitted to the pin by way of the first part co-operating with the second part and thus causes rotation of the first fitment relative to the second fitment and thus defines a new relative angular position between the first fitment and the second fitment at which the rest position occurs, and wherein after actuation of the at least one actuating means with a pivotal force exerted by an operator on the first or second fitment (2, 3) the first part is rotated relative to the second part out of the new relative angular position between the first fitment and the second fitment, in which the rest position occurs, against the application of force by the at least one force storage means and in that case loads same up, characterised in that the at least one actuating means has two screws which can be rotated from outside the hinge and which bear against two projections arranged on the second part. - a first fitment which can be arranged on a first wall element, - a second fitment which can be arranged on a second wall element, - a rotary joint which interconnects the first fitment and the second fitment pivotably about an axis of rotation, wherein the rotary joint has a pin arranged non-rotatably on the first fitment and the first fitment and the second fitment in an adjustable relative angular position with respect to each other are in a rest position from which they are pivotable by an applied force against at least one force storage means and the first fitment and the second fitment in at least one further relative angular position, preferably about +90° or -90° relative to each other, are in an arresting position in which they are releasably arrested to each other against the action of the at least one force storage means, wherein the arresting can be overcome by the application of force by an operator, - an adjusting device actuatable by means of at least one actuating means for adjusting the adjustable relative angular position, - a first part arranged non-rotatably and axially displaceably on the pin, - a second part which during actuation of the adjusting device is non-rotatable relative to the first fitment and rotatable relative to the second fitment, wherein the first part is acted upon with force by the at least one force storage means relative to the second part in such a way that upon actuation of the at least one actuating means the second part functions as a counterpart support for the at least one actuating means and the force exerted on the second part by the actuation of the at least one actuating means is transmitted to the pin by way of the first part co-operating with the second part and thus causes rotation of the first fitment relative to the second fitment and thus defines a new relative angular position between the first fitment and the second fitment at which the rest position occurs,
