1. A coupler assembly for use with a pipe or piping sections, the coupler assembly comprising: a unitary annular body, forming first and second cylindrical openings for surrounding a pipe or piping sections to facilitate forming a fluid-tight seal during use;the unitary annular body comprises a medial portion and first and second longitudinal portions integrally connected to opposite ends of the medial portion; andextending from the first and second longitudinal portions away from the medial portion are respective first and second locking arrangements for securing the coupler assembly to a pipe or piping sections wherein said first and second locking arrangements further comprise a support end and a spaced engagement end located at opposite ends of a locking body, the locking body having an intersecting portion engaged by the longitudinal portion between said support end and said engagement end, said locking body further being transversely oriented to said longitudinal portions. 2. The coupler assembly of claim 1 wherein said medial section further comprises a riser located between and radially projecting opposite first and second stops. 3. The coupler assembly of claim 1 wherein said intersecting portion engaged by the longitudinal portion is substantially medially located along said locking body between side support end and said engagement end. 4. The coupler assembly of claim 3 wherein said locking body is substantially the same material thickness throughout. 5. The coupler assembly of claim 3 wherein said locking body is substantially the same material thickness as said first and second longitudinal portions. 6. The coupler assembly of claim 3 wherein said locking body is substantially the same material thickness as said first and second longitudinal portions and said medial portion. 7. The coupler assembly of claim 3 wherein said coupler assembly further comprises first and second sealing members extending from respective first and second longitudinal portions. 8. The coupler assembly of claim 3 further comprising a gusset member connecting said first and second longitudinal portions with said respective locking arrangement. 9. A coupler assembly for forming a fluid-tight seal during use with a pipe or piping sections, the coupler assembly comprising: a unitary annular body extruded to form first and second cylindrical openings for surrounding a pipe or piping sections during use;the unitary annular body comprises an undulating medial portion and first and second longitudinal portions integrally extruded to opposite ends of the medial portion; andextending from the first and second longitudinal portions away from the medial portion are respective first and second locking arrangements for securing the coupler assembly to a pipe or piping sections;wherein said first and second locking arrangements further comprise a support end and a spaced engagement end located at opposite ends of a locking body, the locking body being transversely oriented to said longitudinal portions such that said support end extending from said engagement end trusses the coupler, strengthening the coupler from deflection or separation during use. 10. The coupler assembly of claim 9 wherein said undulating medial section further comprises a riser located between and radially projecting opposite first and second stops. 11. The coupler assembly of claim 9 wherein said locking body is substantially the same material thickness throughout. 12. The coupler assembly of claim 9 wherein said locking body is substantially the same material thickness as said first and second longitudinal portions. 13. The coupler assembly of claim 9 wherein said locking body is substantially the same material thickness as said first and second longitudinal portions and said undulating medial portion. 14. The coupler assembly of claim 9 wherein said coupler assembly further comprises first and second sealing members extending from respective first and second longitudinal portions. 15. The coupler assembly of claim 9 further comprising a gusset member forming a fillet with said locking arrangement by connecting said first and second longitudinal portions with said respective locking body, the gusset member enhancing the stiffness of the locking arrangements, thereby increasing the separation resistance of the coupler assembly during use. 16. A coupler assembly for forming a fluid-tight seal during use with a pipe or piping sections, the coupler assembly comprising: a unitary annular body extruded to form first and second cylindrical openings for surrounding a pipe or piping sections during use;the unitary annular body comprises a medial portion and first and second longitudinal portions integrally extruded in opposite ends of the medial portion; andextending from the first and second longitudinal portions away from the medial portion are respective first and second flex members having relatively flexible material structure relative to the remaining unitary annular body, allowing for rotational movement about the flex member, the flex member further for securing the coupler assembly to a pipe or piping sections, the flex members transversely oriented radially inward through a first region then expanding radially outward through a second region wherein said flex members further comprise a first material having a first durometer value and said medial portion and longitudinal portions having a second material having a second durometer value wherein said second durometer value is higher than said first durometer value. 17. The coupler assembly of claim 16 wherein said first material has a durometer value ranging between 40 and 60 on a shore A scale and said second material has a durometer value ranging between 35 and 50 on a shore D scale. 18. The coupler assembly of claim 16 wherein said flex members, said medial portion, and longitudinal portion have substantially the same material thickness. 19.
