Abstract
Abstract A tube closure device comprising bendable members each having a pair of arms connected together by integral hinges. Coacting latch arrangements are disposed on the extending ends of the arms to latch the arms over sections of flexible tubes which are placed under compression via the closure devices. A raised floor section on at least one of the arms serves to compress and sealingly enclose the tubes such that residual pressures are provided in a closure.
