A first released connector part (110) to establish a fluid connection with a second connector part comprises a valve (111) with a valve thirst (112),The valve thirst comprising a valve chamber (116) and a circular opening with a circumferential sealing lip (114);A valve element (113),The valve element is provided in the valve chamber and can close the circular opening of the valve seat when pushed against the circular opening; and a resilient element (115) which subjects the valve element to a pressure force by pushing the valve element Against the circular opening of the valve seat. The valve element also comprises a circumferential wall around the circular opening, located on the side of the circular opening opposite the valve chamber. The circumferential wall forms a concave receptacle (118) to receive a corresponding connecting cone from a second connecting piece,Having the concave receptacle shaped like a cone truncated and turned away from the valve chamber, the circular opening being located at the center of the concave receptacle. A second connected part revealed (150) to establish a fluid connection with the first connector part comprises a circular truncated cone (151) to receive a corresponding concave receptacle from a first connector; a recess (153) at the tip of the truncated cone to trigger a Valve element of a first connector part;And a fluid supply conduit (152). The fluid feed line has one or more exits (154) opening at least partially towards the surface of the cone carcase (151).
