The generic document DE 2 015 723 A1 discloses various options for attaching a guide channel to a leaf. Specifically, the guide channel may include an elastic rib with a retaining hook, which can be fitted behind a groove in the leaf profile. The elastic rib can be deflected using a dowel, screw, or wedge. The disadvantage of known hardware is that it is often structurally complex, cannot be reversibly separated, and / or cannot be intuitively assembled. Objective of the invention Therefore, the objective of the invention is to provide a fitting that avoids the disadvantages of the prior art. Description of the invention This objective is achieved according to the invention by means of a fitting according to claim 1, a window or a door according to claim 12 and a method according to claim 14. The objective of the invention is achieved by means of a fitting for a window or door, which can be mounted in a first groove in the profile of a window or door sash. The fitting has a first arm that can be mounted parallel to the extension of a sash sash. The fitting has a retaining portion with a first retaining hook (elastic rib with hook) on the first arm. In addition, the fitting has a thrust body on the first arm. The retaining portion and the thrust body can be moved relative to each other along the longitudinal axis of the first arm from a disengaged position to a mounted position. In the disengaged position, the thrust body does not support the first retaining hook, so it can be moved, particularly radially, preferably inwards.In the mounted position, the thrust body supports the first retaining hook so that it cannot move, particularly radially, preferably inwards, and is securely engaged behind a first rib of the first profile groove. A chamfer is configured between the retaining part and the thrust body, through which the retaining part is transferred from the loose to the mounted position. This allows the fitting to be securely attached to the leaf and at the same time is easy to assemble, particularly without tools. Preferably, the fitting can be separately mounted on the sash and removed non-destructively. The fitting can be configured for tool-free assembly and disassembly. Preferably, the retaining part is fixed to the thrust body. Even more preferably, all parts of the fitting are fixed to each other so that the fitting can be mounted very quickly to the sash. In a particularly preferred design of the fitting, the first retaining hook is pre-tensioned, specifically radially inwards. This allows the first retaining hook to be easily inserted into the first groove of the profile when the fitting is placed in the first groove. More preferably, the fitting has a second retaining hook that faces the first retaining hook. The second retaining hook is movable in the loose position, particularly radially, preferably inwards, and in the mounted position is immovable, particularly radially, preferably inwards, so that it can be securely engaged behind a second rib of the first profile groove (facing the first rib). As an alternative or in addition to pre-tensioning the first retaining hook, the second retaining hook can be pre-tensioned, particularly radially inwards, to facilitate partial insertion of the fitting into the first profile groove. The retaining portion may have a clamp with a U-shaped cross-section, the first retaining hook being configured on a first arm of the clamp. The second retaining hook is preferably configured on a second arm of the clamp. The retaining portion may be configured as a clamp with a U-shaped cross-section. The retaining portion is preferably configured as a single piece (integrally). In a particularly preferred embodiment of the invention, the retaining portion is configured in the form of a carriage. The retaining portion may be configured in the form of a cap. The fitting may include a locking mechanism, which restricts the retaining part's movement in the mounted position or locks it permanently in place. This prevents the retaining part from being released and unintentionally moved to the disengaged position. Preferably, the locking mechanism is detachable, particularly tool-free, to allow the retaining part to be moved to separate the fitting. The locking mechanism can be detached by sliding a bevel firmly along the longitudinal axis of the first arm. Ideally, the locking mechanism secures the retaining part in both the disengaged and mounted positions. The locking mechanism may be configured as a single piece within a housing or a portion of the hardware housing. Preferably, the hardware has a two-piece housing. The two housing portions may be configured as identical parts. Preferably, the fitting has a drive rod connection that can be movably linked to a drive rod of the fitting, wherein the drive rod connection is immovably locked in the disengaged position by the retaining portion and can be moved in the mounted position. This allows for central locking of the drive rod connection without the need to separate this central locking when the drive rod is first actuated. Since high forces are often required in such separation processes in the prior art, there is always a risk of damaging a gear or other fitting components. This risk does not exist with the variant of the invention described herein. Preferably, the drive rod connection is held in its loose position by the retaining portion. The drive rod connection may have at least one stop against which the retaining portion rests in the loose position. The drive rod connection preferably has two stops, between which the retaining portion is positioned in the loose position to keep the drive rod connection stationary. The fitting can be configured in the form of a locking piece, a gear, a scissor guide, or a tilting latch arrangement. Preferably, the fitting is configured in a corner offset. In this respect, it features a second arm whose longitudinal axis runs perpendicular to the longitudinal axis of the first arm. The second arm may also have a retaining part with a first retaining hook and a thrust body, the hook being able to be moved from the loose position to the mounted position through a chamfer between the retaining part and the thrust body by a displacement of the retaining part in the longitudinal direction of the second arm, wherein the first retaining hook can be moved in the loose position, in particular radially, preferably inwards, and in the mounted position is not movable, in particular radially, preferably inwards, to fit securely behind a first rib and a second profile groove in the mounted position. To simplify the construction of the fitting, the second arm can be configured to be identical to the first arm. The central fixing can be done by means of two stops, with a first stop provided on the first arm for the retention part of the first arm and a second stop provided on the second arm for the retention part of the second arm. Preferably, the retaining portion of the first and / or second arm can be moved towards the corner of the fitting in the mounted position. This creates a covered and protected corner in the mounted position. Furthermore, a verification function is implemented, as it allows for easy visual confirmation that the fitting is correctly mounted to the sash. The objective according to the invention is also achieved by means of a window or a door with a leaf and a fitting described in this case mounted on it. Preferably, the leaf is configured as a tilt and turn leaf. Ideally, the first profile groove is seamlessly integrated with the second profile groove. This allows the hardware to be attached to the sash without damaging it. Specifically, a corner opening in the sash can be eliminated by milling, filing, or similar methods, meaning that assembly can be quick and completely reversible. The objective according to the invention is further achieved by means of a procedure for assembling a fitting, in particular a fitting described in this case, with the following procedural steps: A) placing a first arm of the fitting in a first profile groove of a leaf, wherein a first retaining hook of the fitting, through its deflection, particularly radially, preferably inwards; passes through a first rib of the first profile groove; B) relative displacement of a thrust body of the fitting to a retaining part with the first retaining hook in the longitudinal direction of the first arm, wherein the retaining part is moved from a loose position through a chamfer between the retaining part and the thrust body to the mounted position, in which the first retaining hook is reliably engaged behind the first rib by the thrust body supporting the first retaining hook. The procedure may also include the following procedural stages: C) placing a second arm of the fitting in a first second profile of the leaf, wherein a first retaining hook of a retaining part of the second arm, through its deflection, particularly radially, preferably inwards; passes through a first rib of the second profile groove; B) relative displacement of a push body of the second arm to the retaining part of the second arm in the longitudinal direction of the second arm, wherein the retaining part is moved from a loose position through a bevel between the retaining part and the push body to the mounted position, in which the first retaining hook is reliably engaged behind the second rib by the push body supporting the first retaining hook. In procedure step A) a connection of a first blade drive rod to the first arm can be made and in procedure step C) a connection of a second blade drive rod to the second arm can be made. Other advantages of the invention are apparent from the description and the drawing. Furthermore, the features mentioned above and others explained in more detail below can be used, according to the invention, individually or in any combination. The embodiments shown and described are not intended as an exhaustive list but are merely examples to illustrate the invention.

Figure 5b shows a partially sectioned top view of the window in Figure 4, where a retaining part is in the mounted position. Figure 6a shows a sectioned front side view of the window in Fig. 5a. Figure 6b shows a sectioned front side view of the window in Fig. 5b. Figure 7 shows an isometric view of a fitting housing according to Figures 1 to 6. Figure 8 shows a sectioned side view of the fitting in Figure 5b. Figure 9a shows a partial isometric view of a second example of a window embodiment with fittings arranged on a sash, where a retaining part of the fitting is in the loose position. Figure 9b shows a partial isometric view of the window in Figure 9a, where the retaining part is in the mounted position. Figure 10a shows a cross-sectional view of the fitting mounted on the leaf according to Figure 9a, wherein the cut runs along line BB according to Figure 11a. Figure 10b shows a cross-sectional view of the fitting mounted on the leaf according to Figure 9b, wherein the cut runs along line BB according to Figure 11b. Figure 11a shows a cross-sectional view of the fitting mounted on the blade according to Figure 10a, wherein the cut runs along line DD according to Figure 10a. Figure 11b shows a cross-sectional view of the fitting mounted on the leaf according to Figure 10b, wherein the cut runs along line CC according to Figure 10b. Figure 1a shows a window 10 with a sash 12. A fitting 14 is arranged on the sash 12. The fitting 14 is configured in the form of a corner diverter. The fitting 14 serves to divert the movement and / or force of a first drive rod 16 to a second drive rod 18. The fitting 14 has a first arm 20 and a second arm 22. The arms 20, 22 each have a retaining part 24, 26. The retaining parts 24, 26 can be moved in each case in the direction of the longitudinal axis of the arms 20, 22. In figure 1a, the retaining parts 24, 26 can be placed in a loose position in which the fitting 14 can be easily placed on the leaf 12 and removed from the leaf 12. Figure 1b shows window 10 with fitting 14, where retaining parts 24 and 26 are in the mounted position. In this mounted position, fitting 14 is securely locked to sash 12. Figure 2 shows window 10, where initially an arm, in this case the second arm 22, is placed on the leaf 12 to mount the fitting 14. This first stage of assembly is indicated by an arrow 28 in Figure 2. In Fig. 2 it can also be seen that the fitting has a drive rod connection 30, in this case with a pin 32. The drive rod connection 30 is configured to couple the drive rod 16, in this case with a notch 34. The retaining part 24 has a U-shaped clamp 36 with a first retaining hook 38. The drive rod connection 30 has stops 40, 42 (better seen in figure 7), between which the first retaining hook 38 is arranged in the loose position of the retaining part 24. In this way, the drive rod connection 30 is fixed in a central position. Figure 3 shows window 10, where in a second assembly stage, the other arm, in this case the first arm 20, is placed on the leaf 12. This is indicated by an arrow 44. Thanks to the fixing of the drive rod connection 30 in the central position, the pin 32 can be easily inserted into the notch 34 of the drive rod 16. Figure 4 shows the window 10 with the fitting 14 mounted on the sash 12. To fix the fitting 14 to the sash 12, the retaining parts 24, 26 were displaced in the direction of the longitudinal axes of the arms 20, 22. This is represented in Figure 4 by arrows 46, 48. The retaining parts 24, 26 can be displaced in this respect in any order or simultaneously. After the retaining part 24 has moved into the mounted position, the drive rod arrangement 30 is no longer locked but can be moved. This can prevent the "detachment" of a central fixing that exerts a load on the window 10. Figure 5a shows window 10 with fitting 14, where the retaining part 24 is in the loose position. Figure 5b shows the window 10 as shown in Figure 5a, but the retaining portion 24 of the fitting 14 is in the mounted position. The displacement was made according to arrow 48. From an overview of Figures 5a and 5b, it can be seen that the fitting 14 has a thrust body 50 that supports the first retaining hook 38 in the mounted position so that it cannot retract radially inwards and is engaged behind a first rib 52 of a first profile groove 54 of the sash 12. The transition from the loose position shown in Figure 5a to the mounted position of the retaining portion 24 shown in Figure 5b takes place via a chamfer 56. Figure 6a shows window 10 with the retaining part 24 in the loose position. Figure 6b shows window 10 with retaining part 24 in the mounted position. It can be seen that the profile groove 54 has a first rib 52 and a second rib 58. The first retaining hook 38 engages behind the first rib 52 in the mounted position, and a second retaining hook 60 engages behind the second rib 58 in the mounted position. Figure 6b also shows that fitting 14 has a housing 62. Figure 7 shows housing 62. Housing 62 has identical housing halves 64 and 66. Figure 7 shows the chamfer 56 for radial expansion of the first retaining hook 38 (see Figure 6b). Figure 7 also shows the stops 40 and 42 for center locking. Additionally, Figure 7 shows that housing 62 has a locking hook 68. Figure 8 shows window 10, where it can be seen that the locking hook 68, together with a first locking notch 70, forms a locking assembly 72. When the locking hook 68 (as shown) is engaged in the first locking notch 70, the retaining part 24 is secured in the engaged position. Conversely, if the locking hook 68 is engaged in a second locking notch 74 of the locking assembly 72, the retaining part 24 is secured in the disengaged position. Figure 9a shows another embodiment of a window 10 with a sash 12 and fitting 14 that can be mounted on the sash 12. Fitting 14 has a projection (not shown) on a first arm 20 for one-sided engagement behind a profile groove (not shown). This allows fitting 14 to be mounted on the first arm 20 by pivoting. Figure 9b shows window 10, where a second arm 22 on the sheet 12 performs a displacement of a retaining part 24. The retaining part 24 is configured from plastic in the present embodiment. Figure 10a shows a cross-sectional view of window 10 with fitting 14 in the loose position. Figure 10b shows a cross-sectional view of window 10 with fitting 14 in the mounted position. Figure 11a shows window 10, where the retaining part 24 has retaining hooks 38, 60 in the area of this section view, which are not yet engaged or are only slightly engaged behind the ribs 52, 58. Figure 11b, on the other hand, shows window 10, where the retaining hooks 38, 60 are engaged behind the ribs 52, 58 to fix the fitting 14 to the leaf 12. Taking a general view of all the figures in the drawing, the invention, in summary, relates to a fitting 14 that can be mounted on a leaf 12, a window 10, and a door with said fitting 14, as well as a method for mounting fitting 14. The fitting 14 comprises at least a first arm 20 with a retaining portion 24 and a thrust body 50. The thrust body 50 can be displaced relative to the retaining portion 24 in the direction of the longitudinal axis of the first arm 20 to support a first retaining hook 38 in a mounted position, such that the first retaining hook 38 cannot be deflected inwards in the mounted position. A chamfer 56 is provided between the retaining portion 24 and the thrust body 50, through which the retaining portion 24 can be moved from the mounted position to a disengaged position.In the released position, the first retaining hook 38 is no longer supported by the thrust body 50, so it can be deflected inwards. This allows the fitting 14 to be easily mounted and dismounted on the leaf 12.
