1. An apparatus comprising:
a fitting connector comprising:
a connector part;
a fitting connector body part coupled to the connector part; and
a fitting part coupled to the fitting connector;
wherein the connector part, the fitting connector body part, and the fitting part define a fitting hole extending therethrough; and the fitting part defines positioning groove, a longitudinal snap hole, and a side snap opening in communication with the longitudinal snap hole;

a connector comprising:
a connection end;
a connector body part coupled to the connection end;
a positioning bump;
wherein the connection end and the connector body part define a duct hole extending therethrough; the connection end defines a positioning snap groove; the fitting connector is configured to accept the connection end in the fitting hole; when the connection end is fully inserted into the fitting connector:
the positioning bump is located in the positioning groove;
the longitudinal snap hole is aligned with the positioning snap groove;

a valve, and the valve is coupled to the connector;
a U-shaped positioning snap pin comprising:
a pin base;
a pin body part coupled to the pin base;
a snap protrusion coupled to the pin body part;
wherein the U-shaped positioning snap pin is configured to be partially inserted and fully inserted into the longitudinal snap hole; when partially inserted, the snap protrusion engages the side snap opening and the connector is able to be inserted into the fitting connector;

and when fully inserted and when the connector is inserted into the fitting connector, the pin body part engages the positioning snap groove and the snap protrusion engages a longitudinal snap hole exit.
