A quick connect/disconnect coupling between a female connector and a male connector which is insertable into said female connector, e.g. for connecting a high pressure line to a valve block. The female connector (10) comprises a cylindric space (13) for the cylindrical part (14) of the male connector, the envelope surface of said space being provided with at least one groove (18) for accommodation of resiliently out of and into the cylindrical space movable blocking elements (20). A substantially annular flange (19) is coaxially provided at the outward side of the groove (18) of the female connector, substantially in line with the envelope surface of said space. The blocking means (20) comprise at least three in said groove (18) located metal arc segments, each being biased by an elastic element (21) into an inclined position relative to the symmetrical longitudinal axis of the female connector, said inclined position being the blocking position. In this position, the segments together form a truncated cone, the wide base of which is supported by the outward side of the groove (18), on the radial outside of the flange (19).

L'invention concerne un raccord à couplage/découplage rapide entre un élément de raccord femelle et un élément de raccord mâle qui peut être inséré dans l'élément de raccord femelle, par exemple pour raccorder une ligne sous haute pression à une valve. L'élément de raccord femelle (10) comprend un espace cylindrique (13) pour la partie cylindrique (14) de l'élément de raccord mâle, la surface de l'enveloppe de cet espace étant pourvue d'au moins une rainure (18), dans l'espace cylindrique et hors de l'espace cylindrique de laquelle peuvent entrer et sortir élastiquement des éléments de blocage mobiles (20). Un rebord sensiblement annulaire (19) est disposé sur le côté externe de la rainure (18) du connecteur femelle en étant coaxial avec elle et sensiblement aligné avec la surface de l'enveloppe dudit espace. Les éléments de blocage (20) comprennent au moins trois segments d'arc métalliques disposés dans cette rainure (18), chacun étant amené par un élément élastique (21) dans une position inclinée par rapport à l'axe longitudinal de symétrie du connecteur femelle, cette position inclinée étant la position de blocage. Dans cette position, les segments forment ensemble un tronc de cône dont la base large est supportée par le côté externe de la rainure (18), sur le côté radialement externe du rebord (19).
