Figure 1 shows a window 10 with a wing 12, which has a wing frame 13 , and a frame 14. The wing 12 is connected to the frame 14 via at least one stay scissors (not shown), in particular two stay scissors. The opening scissors on the wing 12 are arranged by a connecting device 16.

Figure 2 shows a part of the connecting device 16. The connecting device 16 has a rail 18, a groove 20 and a cap 22 . The inner contour of the groove 20 is C-shaped in cross section. The rail 18 can be inserted into the groove 20 in a first longitudinal direction 24 . If the rail 18 is in the groove 20 up to a second stop 42 (see also Figure 3a ) inserted, locked in Figure 2 downward and in Figure 2 not immediately visible projection 26 (see also Figure 3b ) in a recess 28 of the groove 20. The latching of the projection 26 in the recess 28 prevents pulling out of the rail 18 against the first longitudinal direction 24. Furthermore, a first stop 30 is formed through the recess 28, which further pushes the rail 18 in prevents the first longitudinal direction 24. The first stop 30 and the second stop 42 together form a stop which, when the connecting device 16 is in the assembled state, prevents the rail 18 from being pushed further in the first longitudinal direction 24.

In the context of the present invention, the rail 18 is referred to as being inserted into the groove 20 if the rail 18 is largely inserted into the groove 20 up to its end position. In this In the state, the projection 26 can at least partially dip into the recess 28.

The groove 20 is part of a profile 32, in particular in the form of an extruded profile. The profile 32 is on the casement 13 (see Figure 1 ) screwed on. The rail 18 inserted into the groove 20 thus has a secure and firm connection to the wing 12 (see Figure 1 ) on.

Figure 3a shows the connecting device 16 in a partially assembled state. Out Figure 3a it can be seen that the connecting device 16 has a spring element 34 . The spring element 34 is designed in the form of a leaf spring. The spring element 34 is connected to the rail 18 via rivets 36, 38 . The rail 34 is in accordance with Figure 3a bent at one end away from the rail 18. When the spring element 34 is not actuated, the longitudinal axis of the spring element 34 runs parallel to the longitudinal axis of the rail 18.

To assemble the connecting device 16, the spring element 34 is partially bent away from the rail 18 in order to stop the projection 26 (see also FIG Figure 3b ) to prevent on an end face 40 of the groove 20.

The insertion of the rail 18 into its end position in the groove 20 is signaled to the fitter by the second stop 42. The second stop 42 is formed on a first arm 44 and a second arm 46 .

Furthermore, the arms 44, 46 engage behind part of the rail 18 in order to prevent the spring element 34 from bending over perpendicularly to the groove base of the groove 20. More precisely, the overbending of the spring element 34 is prevented by a third stop 47 , which is defined by the arms 44, 46 is trained. At least the first arm 44, in particular both arms 44, 46, is / are - as in FIG Figure 3a shown - formed in one piece with the spring element 34, so that the connecting device 16 is particularly easy to produce and structurally simple.

The projection 26 is designed in the form of a pin. The projection 26 is riveted to the spring element 34. The projection 26 has a notch 48 , by means of which the projection 26 can be held in the recess 28, as will be explained below.

Figure 4a shows the connecting device 16 in the fully assembled state. In this state, the cap 22, when the rail 18 is arranged in the groove 20, can be pushed onto the profile 32 to such an extent that the inside of the cap 22 strikes the end face 40 of the groove 20 or the profile 32. The cap 22 can only be fitted into its end position when the projection 26 (see Figure 4b ) in its end position in the recess 28 (see Figure 3b and Figure 4b ) is located.

Figure 4b shows the connecting device 16 in a longitudinal section in the fully assembled end position. Out Figure 4b it can be seen that the cap 22 has a fork 50 which at least in sections has the notch 48 (see also FIG Figure 3b ) of the projection 26 encloses. In the present case, the cap 22 presses the spring element 34 on the rail 18 on the one hand. On the other hand, the fork 50 of the cap 22 holds the projection 26 immovably in the recess 28 .
