• the present invention relates to suspension devices with self-locking jaws, for example used as wall suspensions making it possible to hold an object vertically.
• Such a self-locking jaw suspension device may comprise a base and at least a pair of two jaw blocks mounted to rotate on the base along two parallel axes, with means fixing the gap between the jaw blocks and the base.
• the jaw blocks of the pair of jaw blocks are symmetrical to one another with respect to the median transverse plane which separates them, and have eccentric curvilinear bearing faces developing between a first end remote from the axis and a second end close to the axis.
• the jaw blocks pivot around their respective axes, between a clamping position in which the respective first end portions of bearing faces are opposite one another, close together or pressing one against the other, and a release position in which the respective second end portions of bearing faces are opposite one another to leave a free space between the two jaw blocks.
• the object to be hooked is engaged from bottom to top between the two jaws, spreading them apart, after which the weight of the object tends to rotate the two jaws in the direction of their approximation, the two jaws then clamping the object on both sides and opposing its fall.
• An improvement consists in providing a synchronization device, which ensures the synchronization of the jaw blocks of the pair of jaw blocks according to reverse rotations around their respective axes.
• a synchronization device which ensures the synchronization of the jaw blocks of the pair of jaw blocks according to reverse rotations around their respective axes.

• means such as spacers 32 fix the distance E between the jaw blocks 2 and 3 and the base 1.
• Each of the jaw blocks such as the jaw block 2 is limited by an anterior face 6, a posterior face 7, both planar and parallel to each other, and perpendicular to the respective axis 4, and a peripheral face 8
• the peripheral face portion 8 which is oriented towards the other jaw block is a support face 9, eccentric curvilinear, developing between a first end 10 remote from the respective axis of rotation 4 and a second end 11 close to the axis of rotation.
• the second jaw block 3 comprises a bearing face 12 extending between a first end 13 and a second end 14.
• the axes of rotation 4 and 5 are spaced apart by a suitable distance so that the jaw blocks 2 and 3 can pivot between a clamping position illustrated in FIG. 1 and a release position illustrated in FIG. 2.
• the first respective end portions 10 and 13 of the bearing faces 9 and 12 are opposite one another, close together or bearing one against the other.
• the respective second end portions 11 and 14 of the bearing faces 9 and 12 are opposite one another to leave a free space 15 between the two jaw blocks 2 and 3.
• a synchronization device ensures the synchronization of rotation of the jaw blocks 2 and 3 of the pair of jaw blocks according to reverse rotations around their respective axes 4 and 5, between the clamping position illustrated in FIG. 1 and the release position illustrated in Figure 2.
• the synchronization device comprises a rod 16 with two parallel ends 17 and 18, as best seen in FIG. 3, the ends 17 and 18 being connected to a central portion 19 by two respective bent portions 20 and 21.
• the central portion 19 of the rod can for example be rectilinear, and be arranged near the base 1.

• the second hole 23 is in the area of second jaw block 3 extending between the axis of rotation 5 and the first end portion 13 of the bearing face 12. In the clamping position, the rod 16 is thus arranged in an oblique orientation illustrated in FIG. 1.
• the rod 16 can be given a reverse oblique orientation, by placing the first hole 22 in the area of first jaw block 2 extending between the axis of rotation 4 and the first end portion 10 of the bearing face 9, and by placing the second hole 23 H "nH the area of second jaw block 3 extending between the axis of rotation 5 and the second end portion 14 of the bearing face 12.
• the rotation of one of the two jaw blocks 2 or 3 generates the synchronized rotation of The other of the two jaw blocks 2 and 3, between the clamping and release positions, the rod 16 having a constant length.
• a second stop 24 can be provided, projecting from the base 1, and limiting the displacement of the rod 16 beyond the clamping position: in FIG. 1, the rod 16 is in support against the second stop 24, preventing additional rotation of the jaw blocks 2 and 3 beyond the clamping position.
• this second stop 24 may be useless if, in the tightening position, the first ends 10 and 13 of bearing faces 9 and 12 of the jaw blocks 2 and 3 come to bear against one another at- above the plane passing through the two axes of rotation 4 and 5.

• a tubular spacer 32 is engaged on the screw rod 26, and interposed between the front face 33 of the base 1 and the rear face 7 of the jaw block 2, to determine the spacing E separating the jaw block 2 and the base 1.
• a locking nut 38 may advantageously be provided, mounted on the intermediate portion of the screw rod 26, to ensure a clamping of the base 1 on its two faces.
• the screw 26 with head 27 comprises a proximal part of rod 226 with a smooth external surface and of length slightly greater than the thickness of the jaw block 2 increased by the length of the spacer 32
• the proximal part of rod 226 is connected by a shoulder 326 to the end portion 126 of rod which is itself threaded and of reduced section.
• a washer 138 is engaged between the shoulder 326 and the base 1. This thus improves, at reduced cost, the freedom of rotation of the jaw block 2, and assembly is facilitated.
