The invention relates to a vacuum distribution socket (1) comprising a socket body (2) comprising a central passage (3) with removable and removable vacuum passage control elements (15, 16, 17, 18), and a safety system (5, 6, 7, 8, 9) comprising a valve chamber (6) with a movable valve element (5), an elastic element (7) acting on the valve element (5) and a valve seat (9) cooperating with the movable valve member (5). The internal wall (10) of the valve chamber (6) is shaped to present a wall portion (11) of generally conical or frustoconical shape forming the valve seat (9) against which the valve element (5) is pressed. ) mobile. The taper of the wall portion (11) and the shape (8) of the valve element (5) are chosen so that the valve element (5) comes to cooperate non-sealingly with the valve seat. (9), when the gas passage control elements (15, 16, 17, 18) are removed from the central passage (3) and the valve element (5) is pushed back towards the valve seat (9) ) by the elastic element (7). Use of a vacuum distribution outlet (1) according to the invention to distribute vacuum within a hospital building. Abstract figure: Figure 1 L’invention concerne une prise de distribution de vide (1) comprenant un corps de prise (2) comprenant un passage central (3) avec des éléments de contrôle du passage de vide (15, 16, 17, 18) démontable et extractible, et un système de sécurité (5, 6, 7, 8, 9) comprenant une chambre à clapet (6) avec un élément de clapet (5) mobile, un élément élastique (7) agissant sur l’élément de clapet (5) et un siège de clapet (9) coopérant avec l’élément de clapet (5) mobile. La paroi interne (10) de la chambre à clapet (6) est conformée pour présenter une portion de paroi (11) de forme générale conique ou tronconique formant le siège de clapet (9) contre lequel est repoussé l’élément de clapet (5) mobile. La conicité de la portion de paroi (11) et la forme (8) de l’élément de clapet (5) sont choisis de sorte que l’élément de clapet (5) vi
