Systems and methods for a fluid reservoir for use with a fluid infusion device which is automatically filled are provided. A set connector for use with a fluid reservoir of a fluid infusion device includes a body for defining a fluid flow path out of the fluid reservoir. The body includes at least one locking tab that cooperates with a portion of the fluid infusion device to removably couple the body to a proximal end of the fluid reservoir. The body is movable between a first position, in which the fluid flow path is obstructed, and a second position, in which the fluid flow path is open.

1. A fluid infusion device including a set connector for use with a fluid reservoir of the fluid infusion device, the fluid infusion device comprising: the fluid reservoir including a mounting projection with a movable housing, the housing having a tab;the set connector including a cylindrical body
1. A fluid infusion device including a set connector for use with a fluid reservoir of the fluid infusion device, the fluid infusion device comprising: the fluid reservoir including a mounting projection with a movable housing, the housing having a tab;the set connector including a cylindrical body for defining a fluid flow path out of the fluid reservoir, the body including an exterior surface and an interior surface, the exterior surface having at least one locking tab, at least one pinch surface and at least one relief, the at least one locking tab extends outwardly from the exterior surface and cooperates with a portion of the fluid infusion device to removably couple the body to a proximal end of the fluid reservoir, the at least one pinch surface defined as a substantially concave recess circumferentially adjacent to the at least one locking tab and the at least one relief defined through the exterior surface circumferentially adjacent to the at least one locking tab, the body including a lip that extends outwardly from an inner circumference of the body, the lip defining an aperture that receives the tab of the housing to couple the housing to the body,wherein the body is movable between a first position, in which the fluid flow path is obstructed, and a second position, in which the body moves the tab to open the fluid flow path. 2. The fluid infusion device of claim 1, wherein the body has a top surface opposite a bottom surface, and the at least one locking tab is formed along the exterior surface of the body near the bottom surface. 3. The fluid infusion device of claim 2, further comprising a hollow tubing, the hollow tubing coupled to the top surface of the set connector to define a fluid flow path from the set connector. 4. The fluid infusion device of claim 2, further comprising a hollow tubing, the hollow tubing coupled to the circumference of the body between the top surface and the bottom surface to define a fluid flow path from the set connector. 5. The fluid infusion device of claim 1, wherein the at least one locking tab has a ramp surface to engage a corresponding ramp surface of the fluid infusion device. 6. The fluid infusion device of claim 1, wherein the at least one locking tab has a lock surface to contact a corresponding lock surface of the fluid infusion device to prevent movement of the set connector relative to the fluid reservoir. 7. The fluid infusion device of claim 1, wherein the at least one locking tab comprises two locking tabs formed so as to be spaced apart along a circumference of the body. 8. The fluid infusion device of claim 1, wherein the at least one pinch surface comprises two pinch surfaces formed so as to be spaced apart along a circumference of the body and the two pinch surfaces are each to receive a finger. 9. The fluid infusion device of claim 1, wherein the set connector is needleless. 10. A fluid infusion device including a set connector for use with a fluid reservoir of the fluid infusion device, the fluid infusion device comprising: the fluid reservoir including a mounting projection having a housing that is rotatable between a, closed position and an open position, the housing including a tab;the set connector having a body for defining a fluid flow path out of the fluid reservoir, the body including a top surface, a bottom surface and an exterior surface that extends between the top surface and the bottom surface, with the top surface including a lip that extends outwardly from an inner circumference of the body, the lip defining an aperture that receives the tab of the housing to couple the housing to the body and the bottom surface including at least one locking tab, the at least one locking tab extends outwardly from the exterior surface, and the exterior surface includes at least one pinch surface defined as a substantially concave recess circumferentially adjacent to the at least one locking tab,wherein the body of the set connector is movable between a first position, in which the fluid flow path is obstructed, and a second position, in which the fluid flow path is open, and the body rotates the tab of the housing of the fluid reservoir from the closed position to the open position as the body rotates from the first position to the second position. 11. The fluid infusion device of claim 10, wherein the at least one locking tab has a ramp surface to engage a corresponding ramp surface of the fluid infusion device. 12. The fluid infusion device of claim 10, wherein the at least one locking tab has a lock surface to contact a corresponding lock surface of the fluid infusion device to prevent movement of the set connector relative to the fluid reservoir. 13. The fluid infusion device of claim 10, further comprising a hollow tubing, the hollow tubing coupled to the top surface of the set connector to define a fluid flow path from the set connector. 14. The fluid infusion device of claim 10, wherein the at least one pinch surface is to receive a finger. 15. A fluid infusion device including a set connector for use with a fluid reservoir of the fluid infusion device, the fluid infusion device comprising: the fluid reservoir having a proximal barrel end and a distal barrel end, and including a flange that extends upwardly from a surface of the proximal barrel end, the flange defining at least one groove along an interior surface of the flange; andthe set connector having a piercing device that defines a fluid flow path out of the fluid reservoir, and a body coupled to the piercing device, the body including a first end coupled to the piercing device and an opposite second end, the second end including two locking tabs that cooperate with the at least one groove of the proximal barrel end of the fluid reservoir, each of the locking tabs extending from a second end of the body and including a protrusion that is received within the at least one groove of the fluid reservoir to removably couple the body to the fluid reservoir. 16. The fluid infusion device of claim 15, wherein the body comprises at least one pinch surface at the first end.
