and the contact body 68 appear in the form of two coaxial cylindrical tubes linked to one another but different in diameter the outer diameter of the female tip 69 is larger than the outer diameter of contact body 68 so as to form a shoulder 77 for holding in place a clip 143 designed to ensure the attachment of fluidic contact 3 in the opening of plug 2 of the electrical connector furthermore contact body 68 and female tip 69 are separated by an internal partition equipped with an orifice of communication 76 the inner cavity 72 of female tip 69 of female contact 3 is designed to receive the male tip 101 of contact 5 when the two contacts are coupled thus in order to facilitate this coupling the inner edge of the entry of cavity 72 has a rounded portion 74 which assists the engagement of male tip 101 by correcting any misalignment of the latter relative to the axis 53 of the female contact and prevents injury to the sealing washer provided on the male tip of the male contact as the latter engages in cavity 72 furthermore the outer edge of the entry of cavity 72 has a bevel 73 that assists in the engagement of the outer contour of the female tip in the opening 135 39 of the receptacle 4 of the connector of the mother card or of the chassis in the case of the fluidic connector.
