5. A device for coupling a first conduit and a second conduit comprising:

a. a first male end configured to be inserted into the coupling of said first conduit at a first end, and a second end capable of forming a first joint with an inner sleeve;

b. a second male end configured to be inserted into the coupling of said second conduit at a first end, and a second end capable of forming a second joint with said inner sleeve; and

c. at least two joints each capable of permitting movement in an axial direction and at an angle relative to each conduit, wherein each of said at least two joints has an inner surface and a longitudinal axis, and wherein each of said inner surfaces are curved inwardly with an elliptical curvature when viewed in a cross-section down the longitudinal axis of said at least two joints at said second ends of said first male end and said second male end toward the longitudinal axis of said at least two joints, wherein said inner sleeve has a first flared, elliptical-shaped terminal end on a first side and a second flared, elliptical-shaped terminal end on a second side when viewed in the cross-section down the longitudinal axis of said at least two joints, wherein said inner sleeve is disposed between said first joint and said second joint such that said first side is partially disposed within said first joint and said second side is partially disposed within said second joint, and wherein said elliptical curvature at said second ends of each of said first male end and said second male end are configured to engage the respective said first flared, elliptical-shaped terminal end and said second flared, elliptical-shaped terminal end when said device is in a state consisting of being expanded, being deflected, and a combination of being expanded and deflected.

6. The device of claim 5 further comprising a jacket for preventing intrusion of liquids into said device.

7. The device of claim 5 wherein said first conduit and said second conduit are rigid non-metal conduits.

8. The device of claim 5 further comprising at least a third joint comprising a center joint situated between the first male end and second male end and capable of permitting movement in an axial direction and at an angle relative to each conduit, wherein said inner sleeve is two inner sleeves each having a first flared elliptical-shaped end and a second flared end, and wherein said center joint is disposed around said second flared ends.

9. A device for coupling a first conduit and a second conduit comprising:

a. a first coupling end configured to receive said first conduit at a first end, and a second end capable of forming a first joint with an inner sleeve;

b. a second coupling end configured to receive said second conduit at a first end, and a second end capable of forming a second joint with said inner sleeve; and

c. at least two joints each capable of permitting movement in an axial direction and at an angle relative to each conduit, wherein each of said at least two joints has an inner surface and a longitudinal axis, and wherein each of said inner surfaces are curved inwardly with an elliptical curvature when viewed in a cross-section down the longitudinal axis of said at least two joints at said second ends of said first coupling end and said second coupling end toward the longitudinal axis of said at least two joints, wherein said inner sleeve has a first flared, elliptical-shaped terminal end on a first side and a second flared, elliptical-shaped terminal end on a second side when viewed in the cross-section down the longitudinal axis of said at least two joints, wherein said inner sleeve is disposed between said first joint and said second joint such that said first side is partially disposed within said first joint and said second side is partially disposed within said second joint, and wherein said elliptical curvature at said second ends of each of said first coupling end and said second coupling end are configured to engage the respective said first flared, elliptical-shaped terminal end and said second flared, elliptical-shaped terminal end when said device is in a state consisting of being expanded, being deflected, and a combination of being expanded and deflected.
