The invention concerns a band comprising several rows (6 7, 8) of links (1, 2), each row of link including at least two links traversed by a rod member (3 4) engaged in at least a link of the next row so as to the two rows are linked in articulation. The rod member consists of a pin (3) and a head (4) screwed in a tapped aperture (32) in the pin. The next row of links can be detached by first removing the left link (2) by unscrewing the head (4), then by removing the right link together with the pin (3). The invention is advantageous in that the structure is not visible externally and without any play.

Why it's free to use
- Filed March 16, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 16, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 16, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
