An adapter for removably connecting a tube to an external device comprising:

• a body having one end adapted to be connected to said device, another end adapted to be connected to said tube, an axial bore extending between said ends, an access opening, and an inclined bore communicating between said access opening and said axial bore, and
• access closure means comprising a member adapted to be gripped by one or more fingers of a user, movably mounted on the periphery of said body for movement between a position covering said access opening and a position exposing said access opening,
• resilient sealing means compressably disposed between said body and said movable member at least when said movable member is in said covering position, said sealing means forming a substantially airtight seal between said access closure means and said body about said access opening, one of the outer surface of said body and the inner surface of said movable member having a groove and the other of the outer surface of said body and the inner surface of movable member having a projection in said groove to permit movement of said movable member between said covering and exposing positions, and
• a pressure member mounted on said body and at least partially disposed between said sealing means and said movable member when said movable member is in said covering position, said pressure member having a cam surface normally being resiliently urged transversely away from said sealing means and into the path of movement of said movable member and movable into engagement with said sealing means in response to movement of said movable member over said cam surface.
