  • the walls delimiting the housing 9 thus form an abutment blocking the rotation of the seat carrier 2 relative to the housing 10, preventing its unscrewing relative to the insert 140.
  • the latch 8 is integral in rotation with the seat carrier 2, for example via tabs 88 which extend towards the seat-holder 2 and which cooperate with a longitudinal aliasing formed on the central part of the seat-carrier 2.
  • the screwing system of the first end 12 of the seat carrier 2 on the insert 140 located in the housing 3 of the housing 10 is indexed so that the complete screwing corresponds to the precise positioning of the pin (s) 8 facing the (x) housing (s) 9.
  • connection can be made manually quickly and without tools because a large tightening torque can be avoided due to the safety generated by the locking.
  • the connection systems can be made of plastic (the necessary tightening torque is relatively small and is also suitable for plastic parts).
  • the user manually moves the lock 8 towards the seat-holder 2 (against the force of the spring 7) (cf. figure 3 ).
  • the pin 18 of the lock 8 may include a gripping area facilitating the operation.
  • the user therefore applies two distinct movements for the disconnection (in this embodiment a translation of the lock 8 for unlocking and then rotating the seat carrier 2 for unscrewing)
  • a locking system of this type can also be used for the connection of a hose 15 ( figure 5 ) at the second threaded end 213 of the seat support 2 ( figure 1 ).
  • the end of the hose 15 comprises a threaded head 5 (nut, for example).
  • the head 5 of the hose 15 comprises at least one housing 50 intended to cooperate with one or more locking lugs 66 formed on the ring 6 (cf. figure 6 ).

  • the end of the head 5 pushes the ring 6 towards the housing 10 (against the force of the spring 7 which is located thus compressed).
  • the locking tabs 66 formed on the ring 6 come into housing 50 of the head 5 ( figures 6 and 7 ) which allows the ring 6 to return to its more advanced initial position towards the head 5 (less stress on the spring 7). The system is thus locked correctly automatically to block the rotation of the head 5 relative to the seat-carrier 2.
  • connection can be made manually quickly and without tools because a large tightening torque can be avoided due to the safety generated by the locking.

  • the tabs 66 of the ring out of the housing 50 of the head 5 the rotation of the head 5 relative to the seat carrier 2 is no longer impeded and the user can unscrew the head 5 of the flexible seat carrier 2.
  • the user therefore applies two separate movements for the disconnection (in this embodiment a translation of the ring 8 for unlocking and a rotation of the head 5 of the hose for unscrewing).
  • this first unlocking is made impossible when the hose 15 is connected to the other end of the seat-carrier 2.
  • the head 5 of the hose 15 is connected to the seat-holder 2 (2 nd rapid connection)
  • the head 5 of the hose forms a stop for the tabs 88 of the lock 8 preventing the release of the pins 18 out of the housing 9.
  • this second quick connection (head 5 relative to the seat-carrier 2) is in turn carried out by pushing the ring 6 towards the housing 10 (to remove the tab or tabs 66 of the housing 50).
  • the same spring 7 or return member ensures the return of the two locking elements (latch 8, 18 and ring 6, 66) respectively corresponding to the blocking of two quick connections.
  • the ring 6 comprises a plurality of tabs 66 angularly distributed over its circular periphery intended to be housed in housings 50 of the head 5.
  • the head 5 has more housings 50 than the ring 6 has tabs 66 .
  • the ring 6 has four lugs 66 and the head 5 has eight housings 50. If accidentally, the movable ring 6 is moved towards the housing 10 relative to the head 5 and the head 5 partially unscrews the holder. seat 2, then the ring 6 (automatically pushed by the spring 7 to its previous position) will cause a new cooperation of the tabs 66 in other housing 50.
  • Unlocking the head 5 relative to the seat carrier 2 will be possible only when a number of unscrewing turns will be made between the head and the seat-carrier 2. For example, the unlocking is possible when three or four slots 50 are gone.
  • the quick connection defines several successive locking notches (for example two, three or four notches) between the screwed parts (head 5 and seat holder 2). The user must thus pass these successive notches (by unscrewing sufficiently) before being able to unscrew freely without interference of the lock 6.
  • the ring 6 has a perforated structure or open to allow to drain through its thickness of foreign bodies or water and thus avoid inadvertent jamming of the mechanism.
  • the movable locking parts (latch 8 and ring 6) are preferably located on so-called fixed parts (housing side 10 or seat carrier 2).
  • the first connection becomes non-unlockable .
  • the first connection in order to be able to disconnect the first quick connection (seat carrier 2 and housing 10 or the insert assembly 140-housing 10), the first connection must first have been released (head 5-seat carrier 2 or insert 140) . That is, the hose head 5 must be disconnected first to allow the seat carrier 2 to be disconnected from the housing 10.
  • the mobile part of the locking mechanism (latch (s)) has openings to facilitate the flow of water (drainage) to prevent jamming of sands or various particles that can block the mechanism.
  • leaks F occur before completely unscrewing the corresponding connection (preferably at least two screwing turns before the complete disconnection of the parts 5, 2; 2, 10). These leaks F clearly indicate to the user that the system is poorly connected without generating a dangerous situation (the leak is apparent before the total disconnection, which prevents the hose under pressure to adopt dangerous movements and allows the user to stop in time the disconnection).
  • the invention proposes a simple and very safe quick connection system which makes it possible to overcome a large tightening torque and clamping tools.
  • the invention makes possible the realization of connections (threaded connections) plastic without this being limiting. Likewise, the invention makes it possible to envisage other modes of connection than conventional screwing systems.
  • the device comprises a valve seat-holder which is screwed selectively onto a tapped end of a valve-insert itself mounted in a bore of the housing 10.
  • valve seat is also integrated in the valve insert (that is to say that there is no separate seat carrier, the hose connection head that is screwed directly onto one end of the valve insert).
  • fast connection with selective locking can be provided between the connection head 5 and the end of the insert 140.
  • the locking connection system described above can be used for any connection between the hose on the one hand and the demand valve on the other hand (that the hose comes to connect to a seat carrier of valve or on an insert housing both the flap and the valve seat).
  • the locking connection system described above can be used for any connection between an organ of the seat-carrier type and an on-demand valve provided with a valve insert or other fluidic organ.
  • the locking connection system is not limited to the above examples but can be applied to the connection of any fluidic organ in a breathing gas supply device of a plunger.
