A circumferential opening (1 13a) that extends through a wall of the main tube (110) from the main tube channel (115) to an outer side of the wall of the main tube along a second axis that is angled with respect to the first axis. A male luer member (120) configured to slide over the main tube (110) between a closed position in which the male luer member (120) covers the circumferential opening (113a) and an open position in which the male luer member (120) reveals at least a portion of the circumferential opening (130). A gas permeable filter (151) that is substantially impermeable to liquid.
