   Le manchon suivant   1 'intention-  remédie à cet inconvé- nient. A cet effet, la fermeture du manchon est formée d'au moins trois nattes nui se recouvrent suivant des surfaces concentriques à l'axe et sont percées de trous correspondants nar lesquels nasse un moyen de fixation tel nue des vis à écrous on des rivets à écra-   sement   disposes dans un plan axial, de manière nue le manchon possède dans tous les sens environ la même flexibilité. 



   Le dessin annexé représente à titre   d'exemple   une forme d'exécution de 1.' invention. 



   Le corps 1 du manchon convenablement ondula est pourvu   d'une   fermeture longitudinale permettant de   Tracer   le manchon autour   d'une   articulation à cardan sans devoir démonter celle -ci, La fermeture est   formée   des nattes 2, 3   et 4   qui se superposent plat et fini assurent   l'étanchéité   du manchon en formant un joint à labyrinthe oui   emneche   la graisse   consister   te de passer à travers la fermeture.

   Avantageusement, les pattes viennent de   moulage   et Heur   épaisseur   est telle qu'ensemble, elles ne don- nent pas lieu à la formation d'une surépaisseur   considérable   qui pourrait réduire localement la   flexibilité   du manchon de façon sensible. Il est évident que le nombre de pattes pourrait être supérieur à trois,   s'il   s'agissait d'augmenter l'étanchéité pour une raison spéciale. Les pattes sont gercées de trous   corres-     pondants   5 dans lesquels on place des vis à écrous ou des rivets à écrasement 6 ou un autre   moyen   convenable   pour   serrer les nattes l'une contre l'autre et fermer le manchon. 



   Le manchon possède aux extrémités lesnervures   circu-   1 aires -7   habituelles   servant à   maintenir   en place   fins     colliers   de serrage fixant le manchon sur les   pièces     métalliques

   The following sleeve overcomes this disadvantage. For this purpose, the closure of the sleeve is formed of at least three mats overlap along surfaces concentric with the axis and are pierced with corresponding holes in which a fastening means such as bare nuts or rivets are fitted. crushing arranged in an axial plane, bare the sleeve has in all directions approximately the same flexibility.



   The accompanying drawing shows by way of example an embodiment of 1. ' invention.



   The body 1 of the suitably corrugated sleeve is provided with a longitudinal closure allowing the sleeve to be traced around a cardan joint without having to disassemble the latter, The closure is formed of mats 2, 3 and 4 which are superimposed flat and finished seal the sleeve by forming a labyrinth seal that prevents grease from passing through the closure.

   Advantageously, the tabs have been molded and the thickness is such that together they do not give rise to the formation of a considerable extra thickness which could locally reduce the flexibility of the sleeve significantly. Obviously, the number of legs could be more than three, if it was to increase the tightness for some special reason. The legs are chapped with corresponding holes 5 in which are placed nut screws or crush rivets 6 or other suitable means for clamping the mats together and closing the sleeve.



   The sleeve has at the ends the usual circular 1 -7 ribs used to hold in place thin clamps fixing the sleeve to the metal parts
Of course, the invention is not limited to the embodiment which has been described and shown by way of example, and one would go out of its scope by annulling it proud.
