DETAILED DESCRIPTION

(7) FIG. 1 shows a clawed securing device 1 according to the disclosure comprising a band 2 having two halves 3, 4. On the ends 5 of the halves 3, 4 are respectively arranged clamping jaws 6, wherein respectively opposing clamping jaws 6 of the two halves 3, 4 are connected via at least one clamping element 7. Clamping elements 7 are here represented in the form of screws 8, wherein, in the embodiment shown in FIG. 1, two clamping elements 7 per clamping jaw pair are provided.

(8) FIG. 2 shows an enlarged view of a clamping jaw 6. In the represented illustrative embodiment, the clamping jaw 6 has two brackets 9, wherein respectively the free ends 10 are bent over such that the free end 10 rests on the fixed end 11 of the same bracket 9. In particular, the free end 10 of the bracket 9 rests on that face of the fixed end 11 of the bracket 9 which is facing toward the opposing clamping jaw 6. Through the bending over of the free end 10 of the brackets 9, an empty space 12, as well as a material doubling 13, is formed, wherein in the region of the material doubling 13 are provided openings 14 which receive the clamping elements 7.

(9) For stabilization purposes and as grip protection, it is provided that the clamping jaw 6 has a rim 15, which is bent perpendicular to the face of the clamping jaw 6. The rim 15 is here bent in the direction of the opposing clamping jaw 6. Also the axial rims 16 of the halves 3, 4 are bent radially inward.

(10) In FIG. 3 is shown a half 3, 4, which on the axial rims 16 of the half 3, 4 in each case has a part-circular clawed insert 17. This clawed insert 17 comprises a plurality of claws 18 arranged side by side in the peripheral direction, which are connected to one another. The clawed inserts 17 arranged respectively on the opposing axial rims 16 are inclined toward one another. As a result of the radially inwardly bent axial rims 16, the clawed insert 17 is in bearing contact in the region of a bending edge 19. In addition, the clawed inserts 17 have a radial pretensioning, whereby they are held in position.

(11) Holding fingers 20, which are arranged in the respective end region of a half 3, 4, are provided. These holding fingers 20 are shaped out of the respective half 3, 4 and press the clawed insert 17 against the radially inwardly shaped axial rims 16. This is shown in enlarged view in FIG. 4.

(12) Moreover, there is provided at least one stabilization element 21 (FIG. 2), which stabilizes the claws 18 of a clawed insert 17 in a substantially radially inwardly directed orientation. The stabilization element 21 is likewise shaped out of the material of the respective half 3, 4. A supporting element 22 supports the alignment of the stabilization element 21 in an orientation radially inward. The supporting element 22 can consist, for instance, of an oval reinforcement in the material. Such a supporting element 22 is shown, for instance, in FIG. 2.

(13) In an embodiment, the clawed securing device 1 has recesses 23, which, on the one hand, reduce the material quantity required to manufacture the clawed securing device and, on the other hand, serve for the fastening of pipes. It is here provided that the rims 24 of the recess 23 are bent radially inward in the peripheral direction, whereby a positioning channel for the clawed inserts 17 is formed. These features are shown, for instance, in FIG. 1.

(14) FIG. 5 shows an alternative embodiment of a half 3, 4 of a clawed securing device 1 according to the disclosure. The half 3, 4 has on its ends 5 respectively a clamping jaw 6. These clamping jaws 6 respectively have a bracket 9, which is shaped out of the material of the clamping jaw 6 such that the free end 10 rests on the fixed end 11 of the bracket 9. The bracket 9 extends over the whole of the width of the clamping jaw 6 in the axial direction, so that the substantially entire region of the clamping jaw 6 has a material doubling 13. Two openings 14 are provided in the region of the material doubling 13 for the feed-through respectively of a clamping element 7.

(15) In addition, the clawed securing device 1, in particular the region of the clamping jaws 6, has beads 25, which result in an additional rigidity of the clawed securing device 1. These beads 25 are pressed radially outward out of the material of the clawed securing device 1. In the embodiment shown in FIG. 5, two beads 25 are provided for each clamping jaw 6. Moreover, the free end 9 is shaped such that it recesses the region of the beads 25.

(16) The stabilization elements 21 can also have beads 26, which stiffen the stabilization elements 21. The beads 26 of the stabilization elements 21 are here shaped inward in the radial direction.

(17) Moreover, there is here shown a holding finger 20, which is formed onto the rim 24 of the recess 23 and is arranged substantially in the middle of the half 3, 4 in the peripheral direction. In FIG. 5, no clawed insert is shown. As soon as, in the manufacturing and/or assembly process, a clawed insert 17 is inserted, the holding finger 20 is bent over such that the holding finger 20 holds the clawed insert 17 in position.

(18) The invention is not limited to the previously described embodiments, but can be modified in a number of ways. It is to be understood that the foregoing is a description of one or more preferred exemplary embodiments of the invention. The invention is not limited to the particular embodiment(s) disclosed herein, but rather is defined solely by the claims below.
