Abstract
A means for releasable sealing a flexible conduit is disclosed, having particular use in a conduit connecting multiple blood bags. The conduit contains within a portion of itself a flexible strip or tubular insert. This portion of the conduit is positively closed by folding it back on itself and the closed portion is maintained by a clamping or restraining member. Upon release of the clamping member following a heat sterilization procedure, the conduit is readily opened for fluid flow therethrough. The conduit, which without the insert would normally be fused together as a consequence of the heat sterilization, is open by virtue of the insert being made of a material which does not fuse together under these conditions.
