[ What is claimed is:] [1.] A pipe coupling for coupling adjacent, uncoupled pipe ends, comprising,first and second partial-sleeves each having a longitudinal axis, wherein each said first and second partial-sleeve when viewed cross-sectionally along the longitudinal axis has an inner surface in the shape of an arc, wherein each said partial-sleeve has a first and second longitudinal edge defining a longitudinal arc parallel to said partial-sleeve's longitudinal axis, wherein said inner surfaces of said first and second partial-sleeves are provided around and against the outer surface of said pipe ends so that said first and second longitudinal edges of the first partial-sleeve are proximate to the first and second longitudinal edges of the second partial-sleeve forming a first sleeve around said pipe ends, wherein said first sleeve overlaps in both longitudinal directions said pipe ends, wherein said first sleeve has an inner radius of curvature about equal to the outer radius of curvature of said pipe ends;a third and fourth partial-sleeve each having a longitudinal axis, wherein each said third and fourth partial-sleeve when viewed cross-sectionally along the longitudinal axis has an inner surface in the shape of an arc, wherein each said partial-sleeve has a third and fourth longitudinal edge defining a longitudinal arc parallel to said partial-sleeve's longitudinal axis, wherein said inner surfaces of said third and fourth partial-sleeves are provided around and against the outer surface of said first sleeve so that said third and fourth longitudinal edges of the third partial-sleeve are proximate to the third and fourth longitudinal edges of the fourth half-sleeve forming a second sleeve around said first sleeve, wherein said second sleeve overlaps in both longitudinal directions said pipe ends, and wherein said second sleeve has an inner radius of curvature about equal to the outer radius of curvature of said first sleeve; anda first fixing means for holding said second sleeve in position around and against said first sleeve.
