Fitting for connecting a leaf on one side to a fixed frame of a window or a door, wherein the fitting comprises the following: i) a spring element having a spring element portion; ii) a latching element; iii) a bypass element; wherein the fitting successively allows the following positions: a) a closed position, in which the fitting is closed; b) a tilted position, in which the fitting is opened, wherein the spring element portion engages behind the latching element in the tilted position so that the fitting latches at least against a movement back into the closed position, in order to prevent the leaf from slamming shut; c) an open position, in which the fitting is opened further than in the tilted position, wherein the open position allows a displacement of the leaf; d) the closed position; wherein during the movement from the open position into the closed position, by means of an indirect or direct action of the bypass element, the spring element portion does not latch or latches less strongly on the latching element than in the tilted position, in order to facilitate the movement of the leaf from the open position into the closed position, wherein during the movement of the fitting from the open position into the closed position, the spring element portion is supported on the bypass element as far as the transition of the spring element portion onto the latching element, wherein the latching element is arranged or formed on a control element of the fitting, wherein during the opening and closing of the fitting, the control element is moved in a positively controlled manner by the fitting, wherein the fitting has a scissor stay having a stay arm and a control arm, wherein the control arm, at one end, is indirectly or directly articulated on the stay arm and, at the other end, is indirectly or directly articulated on the control element for the positive control of the control element, wherein during the closing of the fitting from the open position into the closed position, the bypass element and the latching element can be moved toward one another until they are in mutual contact with one another, in order to facilitate the transition of the spring element portion onto the latching element. i) a spring element having a spring element portion; ii) a latching element; iii) a bypass element; wherein the fitting successively allows the following positions: a) a closed position, in which the fitting is closed; b) a tilted position, in which the fitting is opened, wherein the spring element portion engages behind the latching element in the tilted position so that the fitting latches at least against a movement back into the closed position, in order to prevent the leaf from slamming shut; c) an open position, in which the fitting is opened further than in the tilted position, wherein the open position allows a displacement of the leaf; d) the closed position; a) a closed position, in which the fitting is closed; b) a tilted position, in which the fitting is opened, wherein the spring element portion engages behind the latching element in the tilted position so that the fitting latches at least against a movement back into the closed position, in order to prevent the leaf from slamming shut; c) an open position, in which the fitting is opened further than in the tilted position, wherein the open position allows a displacement of the leaf; d) the closed position; wherein during the movement from the open position into the closed position, by means of an indirect or direct action of the bypass element, the spring element portion does not latch or latches less strongly on the latching element than in the tilted position, in order to facilitate the movement of the leaf from the open position into the closed position, wherein during the movement of the fitting from the open position into the closed position, the spring element portion is supported on the bypass element as far as the transition of the spring element portion onto the latching element, wherein the latching element is arranged or formed on a control element of the fitting, wherein during the opening and closing of the fitting, the control element is moved in a positively controlled manner by the fitting, wherein the fitting has a scissor stay having a stay arm and a control arm, wherein the control arm, at one end, is indirectly or directly articulated on the stay arm and, at the other end, is indirectly or directly articulated on the control element for the positive control of the control element, wherein during the closing of the fitting from the open position into the closed position, the bypass element and the latching element can be moved toward one another until they are in mutual contact with one another, in order to facilitate the transition of the spring element portion onto the latching element.
