This creation is that a kind of related safe liquid transmits attachment device comprising a shell and a chock. Shell has a first end, the centre gangway of a second end and Jie's what therebetween； Centre gangway has a upper ring surface, the once working surface of anchor ring and Jie's what therebetween； Upper and lower anchor ring is respectively communicated with the first, second end. Chock is set in what centre gangway, is in elastically deformable, and has a bottom surface and one not through joint-cutting； And it can be converted between one leak-stopping position of what and a drain position. It is not in closely sealed shape through joint-cutting when position what leak-stopping position, and bottom surface contacts lower anchor ring and close central channel； It is not in strut shape, and bottom surface recesses lower anchor ring and opens centre gangway through joint-cutting, for liquid communication when position drain position. Therefore this case has both no needle body and can reduce the risk for stabbing infection, synchronously completes the advantages that quite convenient with connection and infusion.本創作係有關一種安全液體傳送連接裝置，其包括一殼體及一塞塊。殼體具有一第一端、一第二端及一介於其間之中央通道；中央通道具有一上環面、一下環面及一介於其間之工作表面；上、下環面分別連通第一、第二端。塞塊設於中央通道內，呈可彈性變形，並具有一底面及一未貫穿切縫；且可於一止漏位置及一導液位置間變換。當位於止漏位置時，未貫穿切縫呈密合狀，且底面接觸下環面而封閉中央通道；當位導液位置時，未貫穿切縫呈撐開狀，且底面退離下環面而開啟中央通道，以供液體流通。故，本案兼具無針體可減少刺傷感染的風險，與連結及輸液同步完成相當方便等優點。
