Claim 7:
8. 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 a positioning groove, longitudinal snap holes, and each longitudinal snap hole has a side snap opening in communication therewith;

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 two positioning snap grooves; 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 positioning snap groove;

a U-shaped positioning snap pin comprising:
a pin base, wherein the pin base defines a plane;
two pin body parts coupled to and extending from the pin base;
a snap protrusion extending along the plane from each pin body part;

wherein each pin body part is configured to be partially inserted and fully inserted into the longitudinal snap holes; when partially inserted, each snap protrusion engages one of the side snap openings 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 each pin body part engages one of the two positioning snap grooves and each snap protrusion engages a longitudinal snap hole exit.
