The connection member (8) is arranged to be releasably connected to the valve housing (9). Guiding means (44) is provided to positively guide the connection member (8) relative to the valve housing (9) during connection of the connection member (8). A sliding valve (31) is adapted to cover said opening (30) in a closing position and to uncover said opening (30) in an opening position. According to the invention a catching member (43) is arranged during movement of the connection member (8) towards the valve housing (9) to guide the connection member (8) to a position where the connection member (8) engages the valve housing (9) by means of said guiding means (44). Alternatively, a coupling device (47) is provided to connect the connection member (8) to the sliding valve (31) and to release the connection member (8) from the sliding valve (31), respectively, in a predetermined position.

Des moyens de guidage (44) assurent le guidage de l'élément de liaison (8) vers le logement (9) en vue de son branchement. Le robinet-vanne (31) est conçu pour recouvrir une ouverture (30) en position de fermeture et la découvrir en position d'ouverture. Pendant le mouvement de l'élément de liaison (8) vers le logement (9) du robinet-vanne un élément d'accrochage (43) guide l'élément de liaison (8) jusqu'à ce qu'il s'emboîte dans le logement.
