ABSTRACT:
A closure device for a surgical post-operative drainage bag comprises a first panel which is curved and a second panel. The two panels are joined by a hinged connection. The second panel comprises two strip-like portions joined together by an intermediate hinge. When the device is closed, the free edge of the second panel tightly engages within the inside of the lip so as to be placed in a stressed condition and so that a portion of the bag positioned between the inside of the lip and the free edge of the second panel may be secured.
