Dispositif de raccordement de type cartouche et dispositif d'extraction d'un tel dispositif de raccordement . La présente invention concerne un dispositif de raccordement de type cartouche destiné à raccorder une extrémité de conduite à un alésage d'un élément de cir¬ cuit de transport- de fluide comme un élément émetteur ou récepteur de fluide, tel qu'une pompe, un réservoir... L'invention concerne également un dispositif d'extraction du dispositif de raccordement hors de l'alésage de l'élé¬ ment de circuit de transport de fluide. ARRIERE PLAN DE L'INVENTION On connaît des dispositifs de raccordement com¬ portant un insert tubulaire pour être engagé dans une ex¬ trémité de l'alésage et y être retenu par une rondelle d'ancrage, 1 ' insert tubulaire étant pourvu intérieurement de moyens d'accrochage pour assujettir de façon étanche l'extrémité de conduite dans 1 ' insert . L'insert reçoit un poussoir coulissant susceptible d'être enfoncé d'une po¬ sition de connexion de l'extrémité de conduite dans in¬ sert vers une position de dégagement de l'extrémité de conduite hors des moyens d'accrochage. La rondelle d'ancrage possède une circonférence intérieure engagée sur 1 ' insert et une circonférence ex¬ térieure divisée en dents qui sont inclinées par rapport à la direction d'engagement de 1 ' insert dans l'alésage et qui sont agencées pour mordre la surface de l'alésage, de telle manière qu'un effort d'extraction de 1 ' insert hors de l'alésage provoque un arc-boutement des dents s 'oppo¬ sant au retrait de 1 ' insert . Le montage du dispositif de raccordement sur l'élément de circuit se limite ainsi principalement à l'enfoncement de 1 ' insert dans l'alé- sage. Ce montage est simple et rapide. Ainsi montés, les dispositifs de raccordement sont indémontables. En cas d'erreur d'assemblage du dis¬ positif de raccordement, l'élément de circuit doit donc être mis au rebut du fait de cette non démontabilité qui interdit toute correction de l'erreur. l'Cartridge type connecting device and extraction device of such a connecting device. The present invention relates to a cartridge-type connection device for connecting a pipe end to a bore of a fluid-transport cir¬cuit element such as a fluid emitter or receiver element, such as a pump, a The invention also relates to a device for extracting the connecting device from the bore of the fluid transport circuit élé¬ ment. BACKGROUND OF THE INVENTION Connection devices comprising a tubular insert are known to be engaged in an end of the bore and to be retained by an anchoring washer, the tubular insert being internally provided with means hooking to sealingly secure the pipe end in the insert. The insert receives a sliding pusher which can be depressed by a connection po¬ of the pipe end in¬ serves towards a position of release of the pipe end out of the attachment means. The anchor washer has an inner circumference engaged on the insert and an ex¬ inner circumference divided into teeth which are inclined with respect to the direction of engagement of the insert in the bore and which are arranged to bite the surface. of the bore, so that a force of extraction of the insert out of the bore causes an arching of the teeth oppo¬ sing the removal of one insert. The mounting of the connecting device on the circuit element is thus mainly limited to the insertion of the insert into the bore. This assembly is simple and fast. Thus mounted, the connection devices are unmountable. In the event of an error in assembling the coupling device, the circuit element must therefore be discarded because of this non-disassembly which prevents any correction of the error. the
On connaît par ailleurs des dispositifs de rac¬ cordement démontables dans lesquels 1 ' insert est agencé pour être vissé dans l'alésage. Le vissage d'un tel dis¬ positif de raccordement est plus long que l'emmanchement d'un dispositif de raccordement du type précédent et né¬ cessite la réalisation d'un taraudage dans le corps. OBJET DE L'INVENTION II serait donc intéressant de disposer d'un dis¬ positif de raccordement qui puisse être emmanché dans l'alésage de l'élément de circuit tout en restant démon¬ table en cas de besoin. BREVE DESCRIPTION DE L'INVENTION A cet effet, on prévoit, selon l'invention, un dispositif de raccordement de type cartouche pour raccor- der une extrémité de conduite à un alésage d'un élément de circuit de transport de fluide, le dispositif de rac¬ cordement comportant un insert tubulaire et une rondelle d'ancrage de insert dans l'alésage, 1 ' insert étant pourvu intérieurement de moyens d'accrochage de l'extré- mité de conduite et d'un poussoir coulissant monté pour pouvoir être enfoncé dans 1 ' insert d'une position de con¬ nexion vers une position de dégagement de l'extrémité de conduite hors des moyens d'accrochage. La rondelle d'an¬ crage est montée sur le poussoir avec un jeu axial pour être dans un état ouvert et s'opposer au retrait de 1 ' in¬ sert hors de l'alésage lorsque le poussoir est dans ses positions de connexion et de dégagement. L' insert et le poussoir sont agencés pour que le poussoir puisse être enfoncé au-delà de sa position de dégagement dans une po- sition d'extraction dans laquelle 1 ' insert contraint la rondelle d'ancrage dans un état refermé pour permettre l'extraction du dispositif hors de l'alésage. Ainsi, lorsque le poussoir est dans ses postions de connexion et de dégagement, la rondelle d'ancrage s'oppose au retrait de 1 ' insert hors de l'alésage. Lors- que le poussoir est amené dans sa position d'extraction, la rondelle d'ancrage est amenée dans son état refermé de sorte qu'elle ne s'oppose plus au retrait du dispositif de raccordement hors de l'alésage. L'invention a également pour objet un dispositif d'extraction d'un dispositif de raccordement de type car¬ touche du type précédent, 1 ' insert étant reçu dans un alésage d'un élément de circuit et ayant une extrémité opposée au poussoir qui est adjacente à un élément annu- laire d'étanchéité du raccordement avec l'extrémité de conduite. Le dispositif d'extraction comprend un appen¬ dice ayant une extrémité qui est agencée pour être intro¬ duite dans le poussoir et 1 ' insert jusqu'à l'élément d'étanchéité et qui est pourvue extérieurement d'un or- gane d'accrochage de l'élément d'étanchéité, l'appendice étant pourvu d'un épaulement de butée sur une surface ra¬ diale du poussoir séparé de l'organe d'accrochage d'une distance sensiblement égale à celle séparant la surface radiale du poussoir en position d'extraction et l'élément d'étanchéité. Ainsi, l'insertion de l'appendice dans le dispo¬ sitif de raccordement provoque l'enfoncement du poussoir dans sa position d'extraction et, en accrochant l'élément d'étanchéité, permet le retrait simultané du dispositif de raccordement et de l'élément d'étanchéité. D'autres caractéristiques et avantages de l'in¬ vention ressortiront à la lecture de la description qui suit de modes de réalisation particuliers non limitatifs de l'invention. BREVE DESCRIPTION DES DESSINS II sera fait référence aux dessins annexés, parmi lesquels : - la figure 1 est une vue en coupe longitudinale d'un dispositif de raccordement conforme à un premier mode de réalisation de l'invention, - la figure 2 est une vue analogue à la figure 1 illustrant la mise en place du dispositif de raccordement dans un alésage d'un élément de circuit, - la figure 3 est une vue analogue à la figure 1 du dispositif de raccordement en place dans l'alésage de l'élément de circuit, - la figure 4 est une vue analogue à celle de la figure 1, illustrant le retrait du dispositif de raccor¬ dement hors de l'alésage de l'élément de circuit, - la figure 5 est une vue en coupe longitudinale d'un dispositif de raccordement conforme à une variante du premier mode de réalisation de 1 ' invention, - les figures 6 à 8 sont des vues analogues à celles des figures 1 à 4 d'un dispositif de raccordement selon un deuxième mode de réalisation. DESCRIPTION DETAILLEE DE L'INVENTION En référence aux figures, le dispositif de rac¬ cordement conforme à l'invention est destiné à équiper un élément de circuit de transport de fluide pour y raccor- der une extrémité de conduite 200. L'élément de circuit a un corps 100 dans lequel est ménagé un alésage générale¬ ment désigné en 101 qui possède un tronçon d'entrée 102 débouchant d'un côté à l'extérieur du corps 100 et à l'opposé dans un tronçon 103 de diamètre inférieur à ce- lui du tronçon d'entrée 102 et séparé de ce dernier par un épaulement 104. Le tronçon 103 débouche dans un tron¬ çon 105 de diamètre inférieur à celui du tronçon 103 et égal au diamètre externe de l'extrémité de conduite. Le tronçon 105 est séparé du tronçon 103 par un épaulement 106 et débouche à l'opposé dans un tronçon 107 de diamè¬ tre sensiblement égal au diamètre interne de l'extrémité de conduite. Le dispositif de raccordement selon le premier mode de réalisation, représenté aux figures 1 à 4 (pour ne pas encombrer les figures 2 à 4, la totalité des réfé- rences ne figure que sur la figure 1) , comprend un insert tubulaire généralement désigné en 1 et un poussoir tubu- laire généralement désigné en 2. L'insert tubulaire 1 comporte deux tronçons axia- lement successifs, à savoir un tronçon d'entrée et un tronçon de sortie généralement désignés en 3 et 4. Le tronçon d'entrée 3 comporte un manchon interne 5 et un manchon externe 6 qui sont coaxiaux et qui sont reliés l'un à l'autre par un voile annulaire frangible 7 dans une position relative d'utilisation. Le manchon interne 5 reçoit le poussoir 2 comme cela sera détaillé dans la suite de la description et possède une extrémité pourvue d'une face radiale de butée 8 et une extrémité opposée reliée au voile annulaire 7. Le manchon externe 6 possède une extrémité rac¬ cordé au canal interne du manchon externe 6 par une sur¬ face tronconique 9 et une extrémité opposée au niveau de laquelle une extrémité 10 du tronçon de- sortie 4 est en- cliquetée dans le canal interne du manchon externe 6. Le tronçon de sortie 4 a une extrémité 11 opposée à l'extrémité 10 qui est reliée par un voile frangible 12 à une bague 13 recevant un élément annulaire d'étanchéité 14. Le tronçon de sortie 4 délimite un canal 15 possédant une portion élargie du côté de l'extrémité 10 dans laquelle est ménagée une gorge 16 recevant une rondelle d'accrochage 17. De manière classique, la rondelle d'ac¬ crochage 17 est déformable entre un état de repos dans lequel la rondelle d'accrochage 17 a un diamètre interne inférieur à un diamètre externe de l'extrémité de con- duite 200 et un état déformé dans lequel la rondelle d'accrochage 17 a un diamètre interne supérieur à un dia¬ mètre externe de l'extrémité de conduite 200. Le poussoir 2 est reçu dans le manchon interne 5 et possède une extrémité de manoeuvre 18 en saillie de 1 ' insert 1 et, à l'opposé, un nez 19. Le poussoir 2 corn- porte extérieurement du côté du nez 19 une gorge 20 rece¬ vant un redan 21 annulaire interne du manchon interne 5 et définissant une course de coulissement du poussoir 2 par rapport au manchon interne 5 entre deux positions ex- trêmes de coulissement, à savoir une position de con¬ nexion dans laquelle le nez 19 du poussoir 2 est en léger appui contre la rondelle d'accrochage 17 qui est dans son état de repos et une position de dégagement dans laquelle le poussoir 2 est enfoncé et le nez 19 maintient la ron- délie d'accrochage 17 qui est dans son état déformé. L'extrémité de manoeuvre 18 du poussoir 2 est pourvue extérieurement d'une butée 22 destinée à venir au contact de la surface du corps 100 de l'élément de cir¬ cuit . Le poussoir 2 comprend une portion centrale sur laquelle est reçue la circonférence interne d'une ron¬ delle d'ancrage 23 dont la circonférence externe est di¬ visée en dents destinées à mordre la surface de l'alésage 101. La rondelle d'ancrage est reçue avec un jeu axial J entre un épaulement radial 24 du poussoir 2 et la face radiale 8 du manchon interne 5. Ledit jeu axial J est sensiblement égal à la course de coulissement du poussoir 2 entre sa position de connexion et sa position de déga¬ gement . La rondelle d'ancrage 23 est de forme classique tronconique et est déformable entre un état ouvert de re¬ pos dans lequel les dents délimitent un diamètre externe supérieur au diamètre du tronçon d'entrée 102 de l'alé¬ sage 101 et un état refermé dans lequel les dents délimi- tent un diamètre externe inférieur au diamètre du tronçon d'entrée 102. La mise en place du dispositif de raccordement dans l'alésage 101 va maintenant être décrite en réfé¬ rence à la figure 2. Le dispositif de raccordement est introduit dans l'alésage 101 par la bague 13, l'opérateur exerçant l'ef¬ fort d'insertion sur le poussoir 2 au moyen d'un outil 300 comportant un logement 301 borgne pour l'extrémité de manoeuvre 18 du poussoir 2. La profondeur du logement 301 est égale à la distance séparant la face terminale de l'extrémité de manoeuvre 8 et la face opposée de la bague 22. Sous l'effort d'insertion, le poussoir 2 est en position de dégagement de sorte que la rondelle d'ancrage 23 et 1 ' insert 1 sont en butée contre l'épaulement 24 et entraînés par le poussoir 2. Le frottement des dents de la rondelle d'ancrage 23 sur la paroi de l'alésage 101 du au mouvement d'inser¬ tion, amène la rondelle d'ancrage 23 vers son état refer- mé. La bague 13 arrivant au contact de l'épaulement 104, le voile frangible 12 cède sous l'effort d'insertion et la bague 13 glisse sur le tronçon de sortie 4. Le mou¬ vement d'insertion se poursuit, jusqu'à ce que le tronçon d'entrée 3 vienne en butée contre la bague 13, ce qui correspond à l'arrivée de l'outil 300 au contact du corps 100 de l'élément de circuit. Lorsque l'effort d'insertion cesse, le poussoir 2 est ramené dans sa position de connexion par la rondelle d'accrochage 17 revenant élastiquement dans son état de repos. La rondelle d'ancrage 23 tend à revenir vers on état ouvert de repos et à mordre la surface de l'alésage 101, 1 ' insert 1 étant en appui contre la circonférence interne de la rondelle d'ancrage 23 par la face de butée 8 du manchon interne 5. La connexion et la déconnexion d'une extrémité de conduite sont réalisées de manière classique, le jeu axial J et le jeu axial J' (égal au jeu J) existant entre la bague 22 et le corps 100 laissant le poussoir libre de l'Removable connecting devices are known in which the insert is arranged to be screwed into the bore. The screwing of such a dis¬ positive connection is longer than the fitting of a connection device of the previous type and requires the completion of a tapping in the body. OBJECT OF THE INVENTION It would therefore be advantageous to have a positive coupling device which can be fitted into the bore of the circuit element while remaining demonable if necessary. BRIEF DESCRIPTION OF THE INVENTION For this purpose, according to the invention, there is provided a cartridge type connection device for connecting a pipe end to a bore of a fluid transport circuit element, the connecting a tubular insert and an insert anchor washer in the bore, 1 insert being internally provided with hooking means of the pipe end and a sliding pusher mounted to be recessed in the insert of a con¬ nexion position to a release position of the pipe end out of the attachment means. The anchor washer is mounted on the pusher with an axial clearance to be in an open state and oppose the withdrawal of the in¬ sert out of the bore when the pusher is in its connection positions and clearance. The insert and the pusher are arranged so that the pusher can be depressed beyond its release position into an extraction position in which the insert forces the anchor washer into a closed state to allow the extraction of the device out of the bore. Thus, when the pusher is in its connection and release positions, the anchor washer opposes the withdrawal of the insert out of the bore. Lors- that the pusher is brought into its extraction position, the anchor washer is brought into its closed state so that it no longer opposes the removal of the connection device out of the bore. Another subject of the invention is a device for extracting a connecting device of the cartridge type of the preceding type, the insert being received in a bore of a circuit element and having an end opposite to the pusher which is adjacent to an annular sealing member of the connection with the pipe end. The extraction device comprises a device having an end which is arranged to be inserted into the pusher and the insert up to the sealing element and which is provided externally with a dispensing member. attachment of the sealing element, the appendix being provided with a stop shoulder on a ra¬ diale surface of the pusher separated from the fastening member by a distance substantially equal to that separating the radial surface of the pusher in the extraction position and the sealing element. Thus, the insertion of the appendix into the connecting device causes the pusher to be depressed in its extraction position and, by catching the sealing element, allows the simultaneous withdrawal of the connection device and the sealing element. Other features and advantages of the invention appear on reading the following description of particular non-limiting embodiments of the invention. BRIEF DESCRIPTION OF THE DRAWINGS Reference is made to the accompanying drawings, in which: FIG. 1 is a longitudinal sectional view of a connection device according to a first embodiment of the invention; FIG. 2 is a view similar to FIG. 1 illustrating the introduction of the connection device in a bore of a circuit element; FIG. 3 is a view similar to FIG. 1 of the connection device in place in FIG. the bore of the circuit element; FIG. 4 is a view similar to that of FIG. 1, illustrating the withdrawal of the connection device from the bore of the circuit element, FIG. is a longitudinal sectional view of a connecting device according to a variant of the first embodiment of the invention, - Figures 6 to 8 are views similar to those of Figures 1 to 4 of a connecting device according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION With reference to the figures, the connecting device according to the invention is intended to equip a fluid transport circuit element to connect a pipe end 200 to it. a body 100 in which is formed a bore generally¬ ment designated 101 which has an inlet portion 102 opening on one side outside the body 100 and the opposite in a section 103 of diameter less than it is the inlet section 102 and separated from the latter by a shoulder 104. The section 103 opens into a tron¬ çon 105 of smaller diameter than the section 103 and equal to the outer diameter of the pipe end. The section 105 is separated from the section 103 by a shoulder 106 and opens on the opposite side in a section 107 of diameter substantially equal to the internal diameter of the pipe end. The connection device according to the first embodiment, represented in FIGS. 1 to 4 (in order not to encumber FIGS. 2 to 4, all the references FIGS. 1), comprises a tubular insert generally designated 1 and a tubular pusher generally designated 2. The tubular insert 1 comprises two axially successive sections, namely an inlet section and an outlet section generally designated 3 and 4. The inlet section 3 comprises an inner sleeve 5 and an outer sleeve 6 which are coaxial and which are connected to each other by a frangible annular web 7 in a position relative use. The inner sleeve 5 receives the pusher 2 as will be detailed in the following description and has an end provided with a radial abutment face 8 and an opposite end connected to the annular web 7. The outer sleeve 6 has a rac¬ end corded to the internal channel of the outer sleeve 6 by a frustoconical sur¬ face 9 and an opposite end at which an end 10 of the outlet section 4 is engaged in the internal channel of the outer sleeve 6. The output section 4 has an end 11 opposite the end 10 which is connected by a frangible web 12 to a ring 13 receiving an annular sealing element 14. The outlet section 4 delimits a channel 15 having an enlarged portion on the end side 10 in which is formed a groove 16 receiving a hooking washer 17. In conventional manner, the ac¬ hooking washer 17 is deformable between a state of rest in which the round The hooking member 17 has an inner diameter smaller than an outer diameter of the lead end 200 and a deformed state in which the catch washer 17 has an inner diameter greater than an outer diameter of the end. 200. The pusher 2 is received in the inner sleeve 5 and has an operating end 18 projecting from the insert 1 and, on the contrary, a nose 19. The pusher 2 comprises door externally on the side of the nose 19 a groove 20 rece¬ vant an inner annular redan 21 of the inner sleeve 5 and defining a sliding stroke of the pusher 2 relative to the inner sleeve 5 between two extreme sliding positions, namely a position connection in which the nose 19 of the pusher 2 is lightly against the latching washer 17 which is in its rest state and a release position in which the pusher 2 is depressed and the nose 19 keeps the ron- fastening loaf 17 which is in its deformed state. The operating end 18 of the pusher 2 is externally provided with a stop 22 intended to come into contact with the surface of the body 100 of the cir¬cuit element. The pusher 2 comprises a central portion on which is received the inner circumference of a ron¬ delle anchoring 23 whose outer circumference is di¬ referred to teeth for biting the surface of the bore 101. The anchor washer is received with an axial clearance J between a radial shoulder 24 of the pusher 2 and the radial face 8 of the inner sleeve 5. Said axial clearance J is substantially equal to the sliding stroke of the pusher 2 between its connecting position and its release position. ¬ ment. The anchor washer 23 is of conventional frustoconical shape and is deformable between an open state of re¬ pos in which the teeth delimit an outer diameter greater than the diameter of the inlet section 102 of the wise and wise 101 and a closed state in which the teeth define an outer diameter smaller than the diameter of the inlet section 102. The establishment of the connection device in the bore 101 will now be described with reference to FIG. is introduced in the bore 101 by the ring 13, the operator exerting the ef¬ strong insertion on the pusher 2 by means of a tool 300 having a blind housing 301 for the operating end 18 of the pusher 2. The depth the housing 301 is equal to the distance between the end face of the operating end 8 and the opposite face of the ring 22. Under the insertion force, the pusher 2 is in the release position so that the washer anchoring 23 and 1 'insert 1 are in abutment against the shoulder 24 and driven by the pusher 2. The friction of the teeth of the anchoring washer 23 on the wall of the bore 101 due to the insertion movement bring the anchor washer 23 to its closed state. The ring 13 coming into contact with the shoulder 104, the frangible veil 12 yields under the insertion force and the ring 13 slides on the outlet section 4. The insertion movement continues, until that the input section 3 comes into abutment against the ring 13, which corresponds to the arrival of the tool 300 in contact with the body 100 of the circuit element. When the insertion force ceases, the pusher 2 is returned to its connecting position by the catch washer 17 returning elastically in its state of rest. The anchor washer 23 tends to return to the open state of rest and to bite the surface of the bore 101, the insert 1 being in abutment against the inner circumference of the anchor washer 23 by the abutment face 8 of the inner sleeve 5. The connection and the disconnection of a pipe end are carried out in a conventional manner, the axial clearance J and the axial clearance J '(equal to the clearance J) existing between the ring 22 and the body 100 leaving the pusher free from the
coulisser entre sa position de connexion et sa position de dégagement (voir la figure 3) . La bague 22 sert de bu¬ tée et de témoin visuel indiquant à l'opérateur que le poussoir 2 est dans sa position de dégagement . Cette ba- gue 22, si elle n'est pas rompue, témoigne de l'intégrité des éléments internes du dispositif de raccordement et notamment de la rondelle d'ancrage. Le retrait du dispositif de raccordement hors de l'alésage 101 va maintenant être décrit en référence à la figure 4. Le retrait est réalisé au moyen d'un outil 400 comportant un appendice 401 ayant une extrémité 402 pour¬ vue d'un renflement 403 de diamètre externe supérieur au diamètre interne de l'élément d'étanchéité 14 pour pou- voir constituer un organe d'accrochage de celui-ci. L'appendice est pourvu d'un épaulement de butée 404 sur la surface terminale de l'extrémité du poussoir, 2. L'appendice 401 est introduit dans le poussoir 2 jusqu'à ce que l'épaulement 404 vienne en butée de l'ex¬ trémité 18 du poussoir 2. Un effort d'enfoncement prédéterminé supérieur à l'effort de déconnexion (par exemple un coup de maillet) est exercé sur l'outil 400. Le poussoir 2 s'enfonce et la bague 22 se brise. Le poussoir 2 reporte en outre l'ef¬ fort d'enfoncement sur la rondelle d'ancrage 23 et sur la face de butée 8 du manchon interne 5 sur lesquels épau¬ lement 24 arrive en butée, provoquant la rupture du voile frangible 7. Le poussoir 2 se déplace sous l'effort d'en- foncement jusqu'à une position d'extraction (qui est au- delà de sa position de dégagement) en entraînant la ron¬ delle d'ancrage 23 et le manchon interne 5. La portion externe de la rondelle d'ancrage 23 arrive au contact de la surface tronconique 9 qui referme la rondelle d'ancrage 23 et maintient cette dernière dans son état refermé dans lequel elle ne s'oppose pas à l'ex¬ traction du dispositif de raccordement. Le renflement 403 est inséré à force dans l'élé¬ ment d'étanchéité 14. On notera que 1 'épaulement de butée 404 est séparé du renflement 403 d'une distance au moins sensiblement égale à celle séparant la surface radiale du poussoir 2 en position d'extraction et l'élément d'étan¬ chéité 14. Le dispositif de raccordement peut alors être ex- trait de l'alésage en tirant sur l'outil 400 qui entraîne l'élément d'étanchéité 14, 1 ' insert 1 et le poussoir 2, la rondelle d'ancrage 23 étant maintenue dans son état refermé . En variante, comme représenté à la figure 5, le manchon interne 5 est encliqueté dans le manchon externe 6. Le manchon interne comprend ainsi un redan annulaire 30 externe reçu dans une gorge 31 du manchon externe 6 lorsque le manchon interne est dans la position relative d'utilisation et dans une gorge 32 lorsque le manchon in- terne 5 est dans la position correspondant à la position d'extraction du poussoir 2. L'effort d'enfoncement néces¬ saire au passage du redan 30 de la gorge 31 vers la gorge 32 est supérieur à l'effort nécessaire pour briser la ba¬ gue 22. Les éléments identiques ou analogues à ceux pré¬ cédemment décrits porteront des références numériques identiques dans la description qui suit du deuxième mode de réalisation en référence aux figures 6 à 8. Dans le dispositif de raccordement du deuxième mode de réalisation, 1 ' insert 1, la rondelle d'ancrage 17 et l'élément d'étanchéité 14 sont identiques à ceux dé¬ crits en relation avec le premier mode de réalisation. Le poussoir 2 possède une partie externe 50 et une partie interne 51 tubulaires et coaxiales . La partie interne 51 est interne a un diamètre interne supérieur au diamètre externe de l'extrémité de conduite et est reliée à la partie externe 50 par un voile frangible 52 de part et d'autre duquel la partie interne 51 a une portion d'extrémité 53 en saillie de la partie externe 50 et une portion d'extrémité 54 s 'éten¬ dant dans la partie externe 50. La portion d'extrémité 53 constitue le nez du poussoir 2 et comporte une gorge externe 20 pour recevoir le redan annulaire 21 du manchon interne 5. La portion d'extrémité reçoit extérieurement, entre la gorge 20 et l'épaulement radial 24, la rondelle d'ancrage 23. La partie externe 50 constitue l'extrémité de ma¬ noeuvre du poussoir 2 et comporte un épaulement de butée 55 pour le corps 100. Le dispositif de raccordement selon le deuxième mode de réalisation est mis en place de la même manière que celui du premier mode de réalisation. La connexion et la déconnexion d'une extrémité de conduite 200 sont réalisées de manière classique, le jeu axial J (entre la rondelle d'ancrage 23 et l'épaulement de butée 24) et le jeu axial J' (égal au jeu J) existant entre l'épaulement de butée 55 et le corps 100 laissant le poussoir 2 libre de coulisser entre sa position de connexion et sa position de dégagement (voir la figure 7) . L'épaulement de butée 55 sert de témoin indiquant à l'opérateur que le poussoir 2 est dans sa position de dé¬ gagement . Le retrait est réalisé au moyen d'un outil 400 identique à celui décrit en relation avec le premier mode de réalisation excepté en ce que l'épaulement de butée 404 est agencé pour prendre appui sur la surface termi¬ nale de la portion d'extrémité 54 de la partie interne 51 du poussoir 2. L'appendice 401 est introduit dans le poussoir 2 jusqu'à ce que l'épaulement 404 vienne en butée de la portion d'extrémité 54. Un effort d'enfoncement prédéterminé supérieur à l'effort de déconnexion (par exemple un coup de maillet) est exercé sur l'outil 400. Le poussoir 2 s'enfonce, l'épaulement de butée 55 vient au contact de corps 100 et le voile frangible 52 se brise. La partie interne 51 con¬ tinue de s'enfoncer et reporte l'effort d'enfoncement sur la rondelle d'ancrage 23 et sur la face de butée 8 du manchon interne 5 sur lesquels l'épaulement 24 arrive en butée, provoquant la rupture du voile frangible 7. La suite de l'extraction est identique à celle précédemment décrite. On notera que dans ce mode de réalisation un ef¬ fort exercé sur la partie externe 50 ne permet une ex- traction du dispositif de raccordement. Le risque d'une extraction accidentelle à la suite d'un choc ou d'un ef¬ fort d'enfoncement sur cette partie du poussoir est ainsi limité. Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des va¬ riantes de réalisation sans sortir du cadre de l'inven¬ tion tel que défini par les revendications. En variante, les moyens d'étanchéité peuvent être différents et comprendre un joint annulaire logé dans le le canal 15 du tronçon de sortie de 1 ' insert 1. Le tronçon d'entrée et le tronçon de sortie de 1 ' insert 1 peuvent être réalisés en une seule pièce ou être soudés ou collés l'un à l'autre par exemple. La butée 22 est facultative. Le poussoir peut être agencé pour coopérer en po¬ sition d'extraction avec un élément de retenue de 1 ' in¬ sert s 'opposant à un retour du poussoir vers sa position de dégagement. Un effort de retrait exercé sur le pous¬ soir permet alors de retirer également 1 ' insert sans né- cessiter un outil particulier. L'élément de retenue peut comprendre un redan formé intérieurement dans 1 ' insert pour coopérer avec un redan de forme complémentaire for¬ mé extérieurement sur le poussoir. La rondelle d'ancrage peut être élastiquement ou plastiquement déformable entre ses deux états. Les parties interne et externe du poussoir peu¬ vent être encliquetées l'une sur l'autre. slide between its connection position and its release position (see Figure 3). The ring 22 serves as bu¬ tee and visual indicator indicating the operator that the pusher 2 is in its disengaged position. This tab 22, if it is not broken, testifies to the integrity of the internal elements of the connecting device and in particular of the anchor washer. The withdrawal of the connection device out of the bore 101 will now be described with reference to FIG. 4. The withdrawal is carried out by means of a tool 400 comprising an appendage 401 having an end 402 for a view of a bulge 403. of outer diameter greater than the inner diameter of the sealing member 14 to be able to form a fastening member thereof. The appendage is provided with an abutment shoulder 404 on the end surface of the end of the pusher, 2. The appendix 401 is inserted into the pusher 2 until the shoulder 404 abuts the abutment. Ex¬ tremity 18 of the pusher 2. A predetermined driving force greater than the disconnection force (for example a hammer blow) is exerted on the tool 400. The pusher 2 sinks and the ring 22 is broken. The pusher 2 furthermore carries the ef¬ strong depressing on the anchor washer 23 and on the abutment face 8 of the inner sleeve 5 on which épau¬ LEMENT 24 arrives in abutment, causing the rupture of the frangible veil 7. The pusher 2 moves under the effort of enuirement to an extraction position (which is beyond its disengaged position) by driving the ron¬ delle anchor 23 and the inner sleeve 5. The outer portion of the anchor washer 23 comes into contact with the frustoconical surface 9 which closes the anchor washer 23 and holds the latter in place. its closed state in which it does not oppose the ex¬ traction of the connecting device. The bulge 403 is inserted by force into the sealing element 14. It will be noted that the abutment shoulder 404 is separated from the bulge 403 by a distance at least approximately equal to that separating the radial surface of the pusher 2 from extraction position and the sealing element 14. The connecting device can then be extracted from the bore by pulling on the tool 400 which drives the sealing element 14, the insert 1 and the pusher 2, the anchor washer 23 being maintained in its closed state. Alternatively, as shown in Figure 5, the inner sleeve 5 is snapped into the outer sleeve 6. The inner sleeve thus comprises an external annular groove 30 received in a groove 31 of the outer sleeve 6 when the inner sleeve is in the relative position. in use and in a groove 32 when the inner sleeve 5 is in the position corresponding to the extraction position of the pusher 2. The driving force néces¬ required the passage of the redan 30 of the groove 31 to the groove 32 is greater than the force required to break ba¬ gue 22. The elements identical or similar to those previously described will bear identical reference numerals in the following description of the second embodiment with reference to FIGS. 6 to 8 In the connection device of the second embodiment, the insert 1, the anchor washer 17 and the sealing element 14 are identical to those described in connection with the first embodiment. The pusher 2 has an outer portion 50 and an inner portion 51 tubular and coaxial. The inner portion 51 is internal to a diameter internal superior to the outer diameter of the pipe end and is connected to the outer portion 50 by a frangible web 52 on either side of which the inner portion 51 has an end portion 53 projecting from the outer portion 50 and an end portion 54 extending into the outer portion 50. The end portion 53 constitutes the nose of the pusher 2 and has an external groove 20 to receive the annular redan 21 of the inner sleeve 5. The portion of end receives externally, between the groove 20 and the radial shoulder 24, the anchor washer 23. The outer portion 50 is the end ma¬ noeuvre pusher 2 and has a stop shoulder 55 for the body 100. The connecting device according to the second embodiment is implemented in the same way as that of the first embodiment. The connection and the disconnection of a pipe end 200 are carried out in a conventional manner, the axial clearance J (between the anchor washer 23 and the stop shoulder 24) and the axial clearance J '(equal to the clearance J) existing between the abutment shoulder 55 and the body 100 leaving the pusher 2 free to slide between its connecting position and its release position (see Figure 7). The abutment shoulder 55 serves as a control indicating to the operator that the pusher 2 is in its disengaged position. The withdrawal is carried out by means of a tool 400 identical to that described in relation to the first embodiment except that the abutment shoulder 404 is arranged to bear on the end surface of the end portion 54 of the inner portion 51 of the pusher 2. The appendix 401 is introduced into the pusher 2 until the shoulder 404 comes into abutment of the end portion 54. A predetermined driving force greater than the disconnection force (for example a hammer blow) is exerted on the tool 400. The pusher 2 sinks, the abutment shoulder 55 comes to body contact 100 and the frangible veil 52 breaks. The inner portion 51 con¬ continues to sink and deflects the driving force on the anchor washer 23 and the abutment face 8 of the inner sleeve 5 on which the shoulder 24 comes into abutment, causing the rupture The following extraction is identical to that previously described. Note that in this embodiment a strong ef¬ exerted on the outer portion 50 allows an extraction of the connecting device. The risk of accidental extraction as a result of a shock or ef¬ strong depressing this part of the pusher is thus limited. Of course, the invention is not limited to the embodiment described and one can bring va¬ riantes realization without departing from the scope of the inven¬ tion as defined by the claims. In a variant, the sealing means may be different and comprise an annular seal housed in the channel 15 of the outlet section of the insert 1. The inlet section and the outlet section of the insert 1 may be made in one piece or be welded or glued to each other for example. Stop 22 is optional. The pusher may be arranged to cooperate in extraction po¬ sition with a retaining element 1 'in¬ serves opposed to a return of the pusher to its release position. A pulling force exerted on the bush then makes it possible to also remove the insert without needing a particular tool. The retainer may comprise a redan formed internally in one insert to cooperate with a redan of complementary shape for¬ externally on the pusher. The anchor washer can be elastically or plastically deformable between its two states. The inner and outer parts of the pusher can be snapped onto one another.
