The present invention, the fluid conducting portion (20) fluid communication it is designed to penetrate the contact surface (16), so as to conduct a fluid (16) the contact surface of the essentially planar (14) contactor opening (18) sterile cover designed to cover the sterile least partially, the end (20) of the fluid-conducting unit facing the said contact surface and / or the contact surface (16) and (64 coupling device essentially parallel along the (40) coupling direction, is designed to engage (34) the complementary coupling device complementary connector (12), the contact surface (16) and) I include (22). The present invention also relates to (12) complementary connector for connecting in a sterile state to the fluid discharge portion of the fluid supply unit connector (10), and using the connector system, the connector (10).本発明は、流体導通部(20);接触装置(14);本質的に平面状の接触表面(16);接触表面(16)を貫通して、流体を導通させるように設計された流体導通開口(18);前記接触表面(16)および/または該接触表面と対面する前記流体導通部(20)の端部を、少なくも部分的に滅菌状態に覆うように設計された滅菌カバー(64);および結合方向(40)に沿って、相補型コネクタ(12)の相補型結合装置(34)と係合するように設計された、前記接触表面(16)と本質的に平行な結合装置(22)を含む。本発明はまた、コネクタ(10)の流体供給部を流体排出部に滅菌状態で接続するための、コネクタシステム、コネクタ(10)の使用および相補型コネクタ(12)にも関する。
