The fitting arrangement according to claim 2 , wherein the first fitting part is a first hinge part that is adapted to be arranged on a post of the frame at a hinge side of the openable element; the second fitting part is a second hinge part that is adapted to be arranged on the openable element that is openable relative to the frame; wherein the second hinge part, when the openable element is in a closed position, engages with the first hinge part such that separation of the first and second hinge parts is only enabled by movement of the openable element towards an open position.
  14. 14 . The fitting arrangement according to claim 3 , wherein the first fitting part is arranged to two fixation devices, longitudinal center lines of the two fixation devices form a line, and a longitudinal center line of the second part when in the first position is offset from said line by a distance of at least 2 mm.
  15. 15 . A door arrangement comprising a door, a frame and at least one of the fitting arrangements according to claim 1 arranged to the frame and/or the door.
  16. 16 . A method of arranging a fitting arrangement to a frame of an openable element, the method comprising the steps of: arranging a sleeve of a fixation device in an opening in the frame by means of exterior threads on said sleeve; arranging a wall screw through the sleeve and the frame into a wall next to the frame, such that the sleeve is attached to the wall; and arranging a first fitting part on the frame and attaching the first fitting part to the sleeve by a fitting screw engaging with interior threads in a hollow interior on the sleeve.

Description

TECHNICAL FIELD The present disclosure relates to a fitting arrangement, and especially to an arrangement which may be used in relation to the prevention of unauthorized opening of an openable element. BACKGROUND An important security problem of residents and firms is the risk of burglary into their apartments, houses and offices. There is an ongoing development of locks, latch systems and hinges in order to decrease this problem and to obstruct efforts to pry open doors. A common way to pry open a door, which is locked to a frame with a latch, is to force the door away from a doorpost which the latch is connected to, and towards the doorpost where the door is connected via hinges. In such a manner, the door may be moved sufficiently for a tool to be inserted between the door and the frame and then to apply a force onto the door in the opening direction of the door. This may be done with a tool, such as a crowbar. The latch is followingly exposed to a stress from which it eventually may break. One way to counteract this problem is to produce latches with higher strength and/or more sophisticated locking connections between the door and the door frame. Another way is to have a plurality of locking latches on the door. This may however increase cost and complexity for the door installation. Further, for any fitting arranged in connection with a door there may be a need for an improved strength to prevent obstruction at unauthorized opening of the door. Consequently, there is a need for an improved secure arrangement for fittings for doors or other openable elements. SUMMARY It is an object of the present inventive concept to provide an improved solution which alleviates the mentioned drawbacks with present solutions. Furthermore, it is an object to provide a fitting arrangement for a frame of an openable element. The invention is defined by the appended independent claims, with embodiments being set forth in the appended dependent claims, in the following description and in the drawings. According to the inventive concept there is provided a fitting arrangement for a frame of an openable element comprising a first fitting part configured to be arranged onto the frame, and a fixation device. The fixation device comprises a sleeve having exterior threads and interior threads, the sleeve being configured to be attached to an opening in the frame by means of the exterior threads; a wall screw configured to extend through the sleeve into a wall next to the frame, attaching the sleeve to the wall, wherein the wall screw is rotatable relative to the sleeve; and a fitting screw configured to fix the first fitting part to the sleeve by engaging with the inner threads of the sleeve. The openable element may be a door and the frame may be a door frame, which may comprise two doorposts and a lintel. The openable element may be mounted to the frame via hinges. The first fitting part may be mounted onto one of the doorposts. Alternatively, the openable element may be a hatch, a window or the like. The fixation device may in one embodiment comprise two or more sets of sleeve, wall screw and fitting screw. The sets may be used for attachment of the first fitting part together. Alternatively, one or more sets may be used for fixing another part to the frame. The first fitting part may form, or form part of, a lock plate, end plate, latch arrangement, hinge or other kind of fitting for an openable element. The first fitting part may via the sleeve and the wall screw be connected to the wall, and any force exerted on the first fitting may be transported to the wall. The sleeve may have a hollow interior, in which the interior threads may be provided. The sleeve may have one end configured to receive the fitting screw to engage with the interior threads. The sleeve may have a bottom end configured with an opening through which the wall screw may extend, at the same time as it may be configured to provide a fixation between the sleeve and the wall screw when the wall screw is attached to a wall. Especially, the bottom end may be provided with an opening allowing a threaded portion of the wall screw to extend through, while a head portion of the wall screw may not be able to extend through the opening. When the wall screw is screwed into the wall, the sleeve, attached by means of the exterior threads to the frame, may be fixed to the wall. Through the same connection the frame may be fixed to the wall. In one embodiment, the fitting arrangement may further comprise a second fitting part configured to be arranged to the openable element, the second fitting part being configured to engage with the first fitting part. The first and second fitting parts may together form or be part of a lock arrangement, a latch arrangement, a safety arrangement or the like. In such embodiments, the first and second fitting parts may in a first state be movable relative to each other, enabling opening of the door or other openable element, and in a se
