A cet effet, les pattes 4 sont dotées d'une extrémité d'une forme en saillie conjuguée des rainures 7. Les patte s4 peuvent être dotées d'encoches pour permettre leur démontage grâce à un outil conventionnel (type tournevis plat par exemple).The hooking system comprises two grooves 7 formed on two opposite side faces of the body 2 and two tabs 4 or flexible hooking blades integral with the accessory 3, the ends of which are respectively received in the two grooves 7. For this purpose, the tabs 4 are provided with one end of a projecting shape conjugated with the grooves 7. The tabs s4 can be provided with notches to enable them to be removed using a conventional tool (such as a flat screwdriver type).

Les deux rainures 7 peuvent être formées respectivement sur deux faces planes du corps 2 qui sont parallèles à la direction longitudinale A.The two grooves 7 can be formed respectively on two plane faces of the body 2 which are parallel to the longitudinal direction A.

Les deux pattes sont de préférence en matériau plastique et par exemple monobloc avec une partie du corps de l'accessoire 3.The two tabs are preferably made of plastic material and for example in one piece with part of the body of the accessory 3.

Le système d'accrochage comprend en outre une bride 5 de serrage vissées sur l'accessoire 3 et générant un effort sur les pattes 4 dans le sens de leur maintien dans lesdites rainures 7 respectives.The hooking system further comprises a clamping flange 5 screwed onto the accessory 3 and generating a force on the tabs 4 in the direction of their retention in said respective grooves 7.

Par exemple, la bride 5 de serrage comprend une plaque ajourée enfilée sur le corps 2 et en appui sur le corps dans un plan perpendiculaire à la direction longitudinale A. C'est-dire que la plaque comprend un trou par lequel elle est enfilée le long du corps 2 jusqu'à venir en butée sur le corps 2. La plaque ajourée peut comporter comprenant des bordures ou rebords inclinées selon la direction longitudinale et venant en appui contre au moins une partie des pattes 4.For example, the clamping flange 5 comprises a perforated plate threaded onto the body 2 and resting on the body in a plane perpendicular to the longitudinal direction A. That is to say that the plate comprises a hole through which it is threaded along the body 2 until it comes into abutment on the body 2. The perforated plate may include inclined edges or edges in the longitudinal direction and bearing against at least part of the legs 4.

Le vissage de la bride 5 de serrage sur l'accessoire 3 génère un effort des bordures inclinées sur les pattes selon une direction transversale ou oblique à l'axe longitudinal A. Comme visible à la [Fig. 3] et à la [Fig. 4], plusieurs (par exemple quatre) vis 6 peuvent être vissées dans une portion inférieure du boîtier de l'accessoire 3. Ces vis sont par exemple s vissées selon une direction parallèle à l'axe longitudinal, A, par exemple vers le bas du robinet. Ceci génère un effort tendant à remonter le boîtier de l'accessoire 3 et serrer les pattes dans leur rainure 7.The screwing of the clamp 5 on the accessory 3 generates a force of the inclined edges on the tabs in a direction transverse or oblique to the longitudinal axis A. As seen in [ Fig. 3 ] and at [ Fig. 4 ], several (for example four) screws 6 can be screwed into a lower portion of the housing of the accessory 3. These screws are for example s screwed in a direction parallel to the longitudinal axis, A, for example downwardly. tap. This generates a force tending to raise the housing of the accessory 3 and tighten the tabs in their groove 7.

Les contacts brides 5 boîtier de l'accessoire 3 et pattes 4 génèrent par exemple une force à composante verticale (serrage vertical) et latérale forçant le plaquage de l'accessoire 3 contre les parois externes du corps 2 du robinet et générant ainsi la fonction retour en position en cas de déformation.The flange contacts 5, housing of the accessory 3 and tabs 4, for example generate a force with a vertical component (vertical clamping) and lateral, forcing the accessory 3 to be pressed against the external walls of the body 2 of the valve and thus generating the return function in position in case of deformation.

Des préférence le système d'accrochage élastique est dimensionné pour autoriser un débattement angulaire élastique inférieur à 25°, notamment inférieur à 15° de l'accessoire 3 par rapport au corps 2 du robinet par rapport à l'axe longitudinal A. C'est-à-dire que l'accessoire 3 peut rotuler ou pivoter relativement au corps 2 du robinet par rapport à la direction longitudinale.Preferably, the elastic attachment system is sized to allow an elastic angular movement of less than 25 °, in particular less than 15 ° of the accessory 3 relative to the body 2 of the valve relative to the longitudinal axis A. This is that is to say that the accessory 3 can swivel or pivot relative to the body 2 of the valve with respect to the longitudinal direction.

Ce déplacement limité (son retour en position) en cas de sollicitation extérieure ou de déformation n'affecte par la connexion d'un l'organe de raccordement au niveau par exemple d'un raccord 13 de sortie du robinet.This limited movement (its return to position) in the event of external stress or deformation does not affect the connection of a connecting member at the level for example of a connector 13 of the valve outlet.

De préférence également, le système d'accrochage élastique autorise un débattement angulaire élastique de l'accessoire limité lorsqu'il est soumis à un effort inférieur à 20N, au-delà de cet effort le système d'accrochage élastique assurant un blocage de l'accessoire par rapport au corps et/ou une rupture mécanique d'un élément flexible du système d'accrochage (par exemple les pattes 4).Also preferably, the elastic attachment system allows an elastic angular movement of the limited accessory when it is subjected to a force of less than 20N, beyond this force the elastic attachment system ensuring a locking of the accessory relative to the body and / or a mechanical failure of a flexible element of the attachment system (for example the tabs 4).

Comme schématisé à la [Fig. 4] et sans que ceci soit limitatif, le boîtier de l'accessoire 3 peut abriter un indicateur de pression dans la bouteille 10 sur lequel est monté le robinet. Un chapeau 11 de protection ajouré peut être disposé autour de cet ensemble.As shown schematically in [ Fig. 4 ] and without this being limiting, the housing of the accessory 3 can house a pressure indicator in the bottle 10 on which the valve is mounted. A perforated protective cap 11 can be arranged around this assembly.

Cet indicateur 8 visuel peut être une pièce mobile. Le boîtier comprend à cet effet des orifices 9 ou fenêtres de visualisation débouchant sur des faces périphériques du boîtier permettant une visualisation selon une position transversale à l'axe longitudinal A.This visual indicator 8 can be a moving part. The housing comprises for this purpose orifices 9 or viewing windows opening onto peripheral faces of the housing allowing viewing in a position transverse to the longitudinal axis A.

Le dispositif indicateur de pression peut être du type de celui décrit dans le document FR3042586A1 .The pressure indicating device may be of the type described in the document FR3042586A1 .

Tout ou partie du mécanisme et notamment la bride peut être "prémontée" pour faciliter l'installation et la fixation de l'accessoire 3.All or part of the mechanism and in particular the flange can be "pre-assembled" to facilitate the installation and fixing of the accessory 3.

La bride 5 de serrage peut être dotée de forme en saillie sur son pourtour interne pour favoriser son ajustement sur le corps 2 du robinet.The clamp 5 may be provided with a protruding shape on its internal periphery to promote its adjustment on the body 2 of the valve.

L'accessoire peut contenir un organe électronique tel qu'une puce électronique communicante, antenne ou autre.The accessory may contain an electronic component such as a communicating electronic chip, antenna or the like.
