Abstract Arrangement permitting sterilization during engagement of two coupling components. One coupling component comprises a coupling element (1) and the other a coupling housing (2) capable of connection thereto. The arrangement in accordance with the invention comprises a flexible casing arrangement (6) which surrounds at least one part of the coupling element (1). A disinfectant (9) is contained inside the casing arrangement. The casing arrangement is provided with a seal (6a, 7) to interact with an abutment (8) on the coupling housing (2) during an introductory coupling movement between the components, the casing arrangement (6) being capable of being rolled or pulled along the outside of the coupling element (1) during the progressive engagement between the coupling components until they reach a fully engaged position (FIG. 1).
A coupling comprising a coupling element and a coupling housing to be connected with said coupling element said coupling housing including a socket for receiving one end of the coupling element therein, said coupling element having a valve for closing the coupling element at one end thereof, a thin flexible casing which surrounds at least a part of the coupling element and projects axially from said one end thereof, said casing defining together with said coupling element and said coupling housing a cavity for accommodating a disinfection agent therein, and means at the projecting end of said casing for substantially fluid-tight connection of the casing to one end of said coupling housing, said casing allowing said coupling element to be introduced into said socket while passing through the disinfecting fluid.
