- Each of these housings 102, 103 therefore corresponds to a particular relative position of the half-link 2 or 3 which carries the seal 240, with respect to the central body 100.
- figure 31 illustrates a particular arrangement with several ribs 101, 101A, ..., defining as many housings 102, 103, 102A, 103A, ..., and therefore as many positions of the joint 240, and therefore of the half-link 2 or 3 carrier of this seal.
- the figure 32 illustrates an inverse configuration where the finger 223 carries several joints 240 cooperating in turn with the same rib 101. It is thus possible to produce an adjustable link 1 with several discrete positions.
- the model illustrated by the Figures 25 to 30 has three adjustment positions: the shortest with the two half-links 2 and 3 completely retracted into the central body 100, the longest with the two half-links 2 and 3 out at the maximum of the central body 100, and an intermediate position where one of the two half-links is fully retracted into the central body 100, while the other is pulled out to the maximum.
- the races of the fingers 23 attached to the half-links 2 and 3 are different, it is then possible to define two intermediate positions instead of one, depending on whether the user moves the first half-link 2 or the second half-link 3 relative to the central body 100.
- this variant can be modified, in a way similar to that of the figure 9 , to comprise only one adjustment element consisting of one or more fingers 223, or respectively 323, the other fingers 323, respectively 223, then being arranged with only a stop collar or the like forming a stop; the adjustment is then made only on one side.
- This configuration is less favorable in amplitude of adjustment, but may allow the equipment of a watch strap with such an adjustable link disposed directly after the horns, preferably on each side of the watch case.
- the elastic seal 240 is held between the rib 101 and another stop surface, for example another rib of the same type, as visible on the figure 31 .
- the first half-link 2 and the second half-link 3 each comprise at least one finger 223, respectively 323, these fingers each having stop means 32 antagonites making this link 1 adjustable captive.

It comprises at least one attachment corner 202 to the first half-link 2, the figure 33 shows a fastening wedge 202 in a fixed position relative to the first half-link 2, which comprises a notch, or a dovetail, or the like, of profile complementary to that of the wedge 202.
- a resiliently deformable front part in view of the slot or slots comprises at least one adjusting wedge 203 cooperating with at least one adjustment notch 204 of the second half-link 3, among a plurality of such adjustment notches 204 carried by the second half-link 3, the passage from one to the other being possible by compression of the shim 200 resulting from a traction force or thrust in the direction D.
- figure 35 illustrates a variant where the attachment corner 202 is also an adjustment wedge, thus movable relative to the first half-link 2, with respect to adjustment notches 204 carried by the first half-link 2, contrary to the figure 33 where he is not.
- a rib 101 of the central body 100, or a running limiter lug 111 advantageously limit the travel of the spring shim 200.
- a tool 205 with a V-end, pushed against the spring retainer 200 makes it possible to tend to close the slot 201, and thus to release the corners 203 of the notches 204, and thus to separate the two half-links, and thus to completely dismantle the adjustable link 1.
- the bearing surface 54 of the masking element is a trunnion 39, carried by two ramps 37 and 38 secured respectively to the first half-link 2 and the second half-link 3, arranged in a cross, so as to move away or closer this trunnion 39 transversely, substantially orthogonal to the direction D, during the approximation or spacing of the half-links.
- the flanges 51 each comprise a screw 53, constituting a bearing surface 54, the end of which is housed in a lateral groove, constituting a complementary bearing surface 29, which comprises one of the half-links, for example example the second half-link 3, to adjust the distance of the masking element 5 to the upper face 6: this distance can be constant if this lateral groove is parallel to the direction D, it can be variable, as visible in the change of position illustrated by the Figures 5 and 8 , when the lateral groove is designed to press the masking element 5 at the ends of the first chamber 26 and a second chamber 36 located near the upper face 6 of the adjustable link 1.
