| 摘要 |
The invention concerns a device for the coaxial connection of a first manifold ( 12 ) comprising a protrusion ( 18 ) able to be received in a neck ( 22 ) on a second manifold ( 14 ). The device is produced in the form of an open collar ( 10 ) produced from an elastically deformable material and having a bottom ( 36 ) extended by two arms ( 38 ) having respective ends which define the opening of the collar. The collar is provided with retaining stops ( 44, 46, 48 ) and at least one locking member ( 60 ) arranged so as to cooperate with an engagement region ( 34 ) of at least one of the manifolds in order to prevent any accidental extraction of the open collar once fitted. Application in particular to heat exchangers for motor vehicles.
