Abstract: A device for releasably securing and sealing the connectable ends of first and second conduits in a breathing circuit, comprising; a flexible tube manipulatively slidable over the connectable ends of the first and second conduits so as to frictionally embrace the ends of the first and second conduits and releasable secure and seal the conduits against dislodgement and leakage, a first clamp presented at one end of the flexible tube for releasably clamping one end of the flexible tube to the first conduit, a projection extending outwardly from the first clamp and adapted to be embedded in the flexible tube.
