1. A male bayonet connector, comprising:
a first shaft;
a second shaft extending substantially parallel to the first shaft; and
a link connecting the first shaft with the second shaft, the first shaft including:
a first distal end portion having a first sealing surface configured to form a substantially fluid-tight seal with a female connector,
a first proximal end portion opposite the first distal end portion,
a first lumen extending substantially along a first longitudinal axis of the first shaft from the first distal end portion to the first proximal end portion, and
a first channel formed on an outer surface of the first shaft between the first sealing surface and the first proximal end portion, the first channel:
at least partially extending circumferentially around the first longitudinal axis, and
including a first distal wall, a first proximal wall opposite the first distal wall, a first central region disposed between the first distal wall and the first proximal wall, and a first rib extending radially outwardly from the first central region, wherein:
the first distal wall extends proximally from a proximal end of the first sealing surface,
a tapered wall of the first distal end portion extends distally from a distal end of the first sealing surface,
the first sealing surface comprises a substantially cylindrical surface extending from the proximal end of the first sealing surface to the distal end of the first sealing surface, and
the first sealing surface is configured to form the first substantially fluid-tight seal at a location between the first distal wall and the tapered wall.
