2. The connector assembly according to claim 1 , wherein the conduits are configured to allow fluidic communication of the connector with two to four, two to three, or two independent fluid sources.

3. The connector assembly according to claim 1 , wherein the body comprises at least two penetrating elements.

4. The connector assembly according to claim 3 , wherein each penetrating element of the at least two penetrating elements is associated with one of the fluid delivery conduits and each penetrating element extends from the body of the connector.

5. The connector assembly according to claim 1 , wherein the at least one arm has a non-uniform cross-section and a coupler that comprises a hooked end or an inclined surface.

6. The connector assembly according to claim 1 , wherein the first portion has one or more protrusion or rib extending outwardly from a surface, and the second portion has one or more complementary groove or recess formed within a surface, or wherein the second portion has one or more protrusion or rib extending outwardly from a surface, and the first portion has one or more complementary groove or recess formed within a surface.

7. The connector assembly according to claim 6 , wherein the surface feature associated with the first portion is a rail type element and the surface feature associated with the second portion includes a channel that is sized and configured for receiving and reversibly coupling with the rail type element.

8. The connector assembly according to claim 6 , wherein the first and second portions are connected with complementary male and female parts that form a bayonet connection.

9. An infusion set for administering multiple fluids to a subject, the infusion set comprising a base, an insertion portion, and a connector;

wherein the base comprises an adhesive portion, a hub configured to couple with the connector, and at least one lumen configured to receive the insertion portion;

wherein the insertion portion comprises at least one penetrating element comprising a multi-lumen cannula extending from a housing, the at least one penetrating element being coupled to and extending from the base to administer the multiple fluids sub- or trans-cutaneously to the subject when the housing is positioned in the at least one lumen;

wherein the connector comprises a body, at least one arm connected to the body which is configured to couple with the hub of the base, and at least two independent fluid delivery conduits which are configured to allow fluidic communication between at least two independent fluid sources and the at least one penetrating element;

wherein the base defines first and second dents within the at least one lumen that correspond with chamber entrances of the housing and are configured to fluidly couple the at least two independent fluid delivery conduits to separate lumens of the multi-lumen cannula.

10. The infusion set according to claim 9 , wherein the housing has at least two chambers configured to allow fluidic communication between the at least two independent fluid sources and the at least one penetrating element, wherein the at least two chambers are independent from each other.

11. The infusion set according to claim 10 , wherein the base has at least two channels which substantially align with the at least two chambers of the housing and are configured to allow fluidic communication with the at least two independent fluid sources.

12. The infusion set according to claim 10 , wherein each of the at least two chambers of the housing has an opening for fluidic communication with the at least one penetrating element and an opening for fluidic communication with one of the fluid delivery conduits of the connector.

13. The infusion set according to claim 9 , wherein the multi-lumen cannula has a first lumen with a distal end for fluid communication between the placement site and a first fluid source of the at least two independent fluid sources, and a second lumen with a distal end for fluid communication between the placement site and a second fluid source of the at least two independent fluid sources, wherein the first and second lumens are independent from each other.

14. The infusion set according to claim 9 , further comprising a sensor portion, wherein the sensor portion has at least one sensor extending from the base which is configured for determining at least one body characteristic of the subject.

15. The infusion set according to claim 14 , wherein the sensor portion comprises a lumen in the at least one penetrating element for the at least one sensor.

16. The infusion set according to claim 15 , wherein the sensor portion further comprises a groove in the housing and a groove in the base.

17. The infusion set according to claim 9 , further comprising a cap for coupling with said base, wherein the base has at least two channels configured to allow fluidic communication with the at least two independent fluid sources, and the cap has at least one track on its inside surface for coupling with said channels.

18. The infusion set according to claim 17 , wherein the at least one track for coupling with the housing is formed from a membrane material.
