AbstractA connector for affecting aseptic juncture of two bodies for flow of fluid therebetween comprises a female element having a base, a conduit passing through the base, a cylindrical sheath extending from the base and concentrically spaced about a portion of the conduit, an annular exterior wall extending from the base a greater distance than the sheath and concentrically spaced thereabout and pellicular means for sealing the annular exterior wall at a position remote the base, with a male element telescopingly engageable with the female element and including a sole, a conduit passing through the sole and tubular means extending from the sole a greater distance than the conduit and concentrically spaced thereabout. Means are provided for retaining the male and female elements in telescoping engagement. Puncturable pellicular membranes at the extremities of the male and female elements maintain the element interiors in an aseptic condition until the membranes are ruptured when the male and female elements are joined.
