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.

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.
