relates to a coupling system comprising at least one male component and one female component, in which system the male component is inserted into the female component along a longitudinal axis that is common to the male and female components and is retained removably by the female component: the male component comprising an elongate body of substantially cylindrical shape; the female component comprising an elongate body of substantially cylindrical shape and having a longitudinal internal bore of dimensions suited to the insertion and retention of the male component and an open top end; the male component being inserted into the female component through a movement of longitudinal displacement combined at the same time with a rotation by a quarter of a turn; the male component comprising means for blocking rotation and displacement along a longitudinal axis, these means collaborating with complementary stop means present in the female component. ## Claims ### Claim 1 A

cylindrical elongated body having an inner longitudinal bore of dimensions which are adapted to the insertion and retaining of the male component, and an open upper extremity; the male component is insertable into the female component via a simultaneous longitudinal displacement movement and a quarter-rotation movement; the male component including blocking means preventing longitudinal axis displacement and rotation, which cooperate with complementary stopping means present in the female component. ### Claim 2 (depends on 1) The coupling system according to claim 1, wherein the
