For creating and/or releasing a fluid flowable medical threaded connection of the first connecting element (1) and the second connecting element (6), in particular for creating and/or releasing a luer lock connection. Device (100), said device (100) comprising a first receiving device (20) for receiving a first connecting element (1) and a second receiving device (30) for receiving a second connecting element (6). And the first receiving device (20) and the second receiving device (30) are rotatable with respect to each other about a common fastening axis (V) and with respect to each other along the fastening axis (V). Displaceable, the device (100) comprises a first receiving device (so that the first connecting element (1) and the second connecting element (6) are fastened together or the threaded connection is released. 20, 320) and the second receiving device (30) are designed to move relative to each other and the associated first connecting element (1) and second connecting element (6) have a fastening shaft (V). Can be introduced radially (R) into the first receiving device (20) and the second receiving device (30). The invention further relates to a corresponding method. [Selection diagram] Figure 4第１の接続要素（１）及び第２の接続要素（６）の流体流れ可能な医療用螺合接続部を生成及び／又は解除する、特にルアーロック接続部を生成及び／又は解除するための装置（１００）であって、 上記装置（１００）が、第１の接続要素（１）を受ける第１受容装置（２０）及び第２の接続要素（６）を受ける第２受容装置（３０）を備え、 第１受容装置（２０）及び第２受容装置（３０）は、共通の締結軸（Ｖ）の周りに互いに対して回転可能であり、且つ締結軸（Ｖ）に沿って互いに対して変位可能であり、 上記装置（１００）は、第１の接続要素（１）及び第２の接続要素（６）が共に締結され又は螺合接続部が解除されるように、第１受容装置（２０，３２０）及び第２受容装置（３０）を互いに向かって相対移動するように設計され、 関連する第１の接続要素（１）及び第２の接続要素（６）は、締結軸（Ｖ）に対して半径方向（Ｒ）で第１受容装置（２０）及び第２受容装置（３０）に導入することができる。本発明は更に、対応する方法に関する。【選択図】図４
