Abstract
A coaxial connection having a device and 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.
