Description: H OLDER FOR ATTACHMENT OF OBJECTS. TECHNICAL FIELD: The present invention relates to a holder for holding objects by means of a fastening member, which holder has an anchoring section which is provided with at least one engagement surface in the shape of an inwardly facing circumferential surface which is arranged, when mounted, to be biased onto an outwardly facing circumferential surface of the fastening member and is formed by a female part in the shape of a recess, wherein the holder is provided with holding means for holding objects. BACKGROUND OF THE INVENTION: The conventional technique for holding objects to an existing fastening member, such as a screw joint, is to clamp the holder between a screw head or, alternatively, a nut and a fastening surface (see Fig. 1). This is utilized, for example, utilized in the vehicle industry for holding cabling, wherein the holder is constructed as an angularly bent sheet-metal bracket which is provided with a hole, through which the screw is brought. The screw member may, for example, form part of a vehicle beam construction for the purpose of keeping structural members together. In this regard, the holder must be mounted at the same time as the preparation of the screw joint, wherein there is a risk of the holder changing position to an incorrect position during tightening, due to the friction between the holder and parts in the screw joint. Furthermore, the holder is exposed to the same tightening forces as the screw joint itself, which demands a great deal of the physical properties of the holder material. Likewise, the screw joint must be unfastened when the holder is to be exchanged. Apart from good physical properties, which in practice means that the holder must be constructed in metal, it is required that the holder does not cause corrosion problems, which easily arise between surfaces lying closely together. SUMMARY OF THE INVENTION: The object of the present invention is to eliminate the above-mentioned problems and to provide a holder which is easy to mount and later exchange and which can be adjusted and kept in a fixed position. Said object is accomplished by means of a holder according to the present invention, which is characterized in that the anchoring section has a second engagement surface in the shape of a second inwardly facing circumferential surface which is formed by a hole in said bottom surface, wherein said hole is arranged to be biased onto a second section of the fastening member, and that said recess is substantially cylindrical having a circular opening and a bottom surface. BRIEF DESCRIPTION OF THE DRAWINGS: The invention will be further described in the following with an embodiment and with reference to the annexed drawings, in which Fig. 1 shows an example of the previously known technique, Fig. 2 shows a mounting example in the form of an exploded view of a holder according to the invention which is intended to be mounted on a screw joint, Fig. 3 shows an end view of the holder, Fig. 4 shows a cross section through the holder along the line 4:4 in Fig. 3, and Fig. 5 shows a corresponding section through the holder when mounted. PREFERRED EMBODIMENT: As is best apparent from Fig. 2, the holder 1 according to the invention consists of an anchoring section 2, by means of which the holder is arranged to be fastened to a fastening member 3, such as a screw joint, which in the shown example is partly shown in the form of a screw 4, a nut 5 and a washer 6. The fastening member extends through a hole in a fastening wall 7, which in the shown example is formed by a beam 8 in, for example, a motor vehicle. In the shown example, the holder 1 discloses an arm 9 and holding member 9, which in the shown example is constituted by a bundle band which extends through a hole 10 in the end of the arm and is intended to hold cabling 11, of which one cable is shown. With reference to Figs. 2 to 5, it can be established that the anchoring section 2 is formed as a sleeve-shaped section having a first engagement surface in the shape of a circumferential surface 12, which in the shown example is arranged in a recess 13 of the anchoring section. In the shown example, the circumferential surface is substantially cylindrical having a circular opening 14 and a cylinder envelope surface, which constitutes the circumferential surface 12, and a bottom surface 15 which forms a stop face for axial position-holding of the holder, more precisely so that the symmetry axis 16 of the engagement section 2 coincides with the longitudinal axis of the fastening member. In the shown example, the holder also discloses a second circumferential surface 17 which forms a second engagement surface. In this manner, a through, substantially cylindrical, opening is formed in the holder. Fig. 5 shows the holder when mounted on the fastening member 3. The fastening member is mounted on the beam 8 and extends through a hole 18 in the fastening surface 7, wherein the nut 5 is tightened with the washer 6 being arranged between the nut and the fastening surface. In this regard, the screw 4 protrudes with a threaded envelope surface 19 outside the nut 5. The holder 1 is dimensioned to be fastened to the screw member 3 by means of press fit onto its nut 5, more precisely its circumferential surface, wherein the dimension of the circumferential surface 12 of the holder substantially corresponds to, more precisely is slightly less than, the largest transverse dimension of the nut 5. Furthermore, the depth of the recess in axial direction is less than the height of the nut. As regards an angular nut such as is shown in Fig. 5 and whose contour line is indicated in Fig. 3, a slight deformation of the circumferential surface 12 of the holder takes place in practice, which results in an axial frictional engagement as well as a rotatably locked form engagement. The axial engagement is enforced by means of the second cirumferential surface 17, which correspondingly is dimensioned for press fit onto the envelope surface 19 of the threaded screw. In the second circumferential surface 17 as well, a certain degree of deformation takes place in the holder material in practice, which enforces the engagement effect. To this end, the holder 1 is preferably constructed in a softer material than the existing fastening member, for example light metal, plastics or the like. Thermoplastics, as well as thermosetting plastics having a suitably balanced hardness, are possible, for example polyethylene, polypropylene, PVC, polyester, acrylic etc. By means of the engagement of the second circumferential surface, the stability of the holder mounting increases due to the large "engagement length", viewed along the symmetry axis 16. The mounting of the holder 1 takes place simply by means of hammer strokes in axial direction against the plane impact surface 20 of the holder which is provided with, for example, an intermediate sleeve, until the end surface 21 of the nut bottoms against the bottom surface 15. Before the mounting, the holder rotational position in relation to the axis 16 can be selected freely and fixed by means of the mounting. Dismounting is preferably carried out by means of rotation and axial pulling by means of, for example, tongs. The invention is not limited to the embodiment which is described above and shown in the drawings. For example, the holder may be used in a construction which is not arranged in a vehicle. The nut may have another outer form.
