Patent ID: 7325841

Claim:
A coaxial connection device of two manifolds comprising: a first manifold having a protrusion on an end region of the first manifold; a second manifold having a neck on an end region of the second manifold; the first and second manifolds disposed about an axis (XX); an engagement region on the end region of the first or the second manifold; an elastically deformable open collar having a bottom; the open collar including two flexible arms extending from the bottom and defining an opening of the open collar; the flexible arms separating radially apart from one another with respect to the axis (XX) when the open collar engages at least one of the manifolds while moving in an insertion direction (D) and the flexible arms moving towards one another after movement continues in the insertion direction (D); axial holding or retaining slots located on the open collar such that the slots exert an axial abutment against the protrusion of the first manifold and the neck of the second manifold; and at least one locking member situated in a region of the bottom of the open collar and cooperating with the engagement region of the first or second manifold to prevent the open collar from moving in a direction opposite to the insertion direction (D).
