Device for connecting and repairing pipe sections (R1; R2) of a pipe, more particularly an HDPE pipe, comprising: - at least one clamping sleeve comprising an attachable sealing element and a pipe clamp surrounding the sealing element for producing a connection between the pipe sections (R1; R2) of a pipe; wherein, arranged preferably at the end on the sealing element, the at least one clamping sleeve is provided with, preferable double, sealing lips (11'; 11") for sealing between the pipe and the clamping sleeve; - at least two coupling rings (2'; 2") in mechanical effective connection with the clamping sleeve for fastening the coupling device on the pipe; - at least two collar bearings (3'; 3") with, in particular, a U-shaped cross-section; wherein the at least two coupling rings (2'; 2") have a U-shaped, M-shaped or V-shaped cross-section; wherein arranged in a receiving area of the at least two coupling rings (2'; 2") is a plurality of gripping teeth (15'; 15"), preferably arranged in at least one row; and wherein the at least two coupling rings (2', 2") arranged on both sides in relation to the clamping sleeve can each be received in one of the collar bearings (3', 3") so that tensile forces acting in the assembled state on the pipe sections (R1; R2) are compensated to form an axially high tensile strength repair coupling, and so that the sealing area achieved through the clamping sleeve and the axial tensile strength achieved through the coupling rings (2'; 2") is spatially separated to prevent negative influencing of the impermeability of the sealing element; wherein a third axial extension (z) of a respective coupling ring (2', 2") is at a ratio of preferably 1 to 5 to 10, more preferably 2 to 4 to 10, most preferably around 3 to 10 in relation to a second axial extension (y) of the clamping sleeve. - at least one clamping sleeve comprising an attachable sealing element and a pipe clamp surrounding the sealing element for producing a connection between the pipe sections (R1; R2) of a pipe; wherein, arranged preferably at the end on the sealing element, the at least one clamping sleeve is provided with, preferable double, sealing lips (11'; 11") for sealing between the pipe and the clamping sleeve; - at least two coupling rings (2'; 2") in mechanical effective connection with the clamping sleeve for fastening the coupling device on the pipe; - at least two collar bearings (3'; 3") with, in particular, a U-shaped cross-section; wherein the at least two coupling rings (2'; 2") have a U-shaped, M-shaped or V-shaped cross-section; wherein arranged in a receiving area of the at least two coupling rings (2'; 2") is a plurality of gripping teeth (15'; 15"), preferably arranged in at least one row; and wherein the at least two coupling rings (2', 2") arranged on both sides in relation to the clamping sleeve can each be received in one of the collar bearings (3', 3") so that tensile forces acting in the assembled state on the pipe sections (R1; R2) are compensated to form an axially high tensile strength repair coupling, and so that the sealing area achieved through the clamping sleeve and the axial tensile strength achieved through the coupling rings (2'; 2") is spatially separated to prevent negative influencing of the impermeability of the sealing element; wherein a third axial extension (z) of a respective coupling ring (2', 2") is at a ratio of preferably 1 to 5 to 10, more preferably 2 to 4 to 10, most preferably around 3 to 10 in relation to a second axial extension (y) of the clamping sleeve. wherein the at least two coupling rings (2'; 2") have a U-shaped, M-shaped or V-shaped cross-section; wherein arranged in a receiving area of the at least two coupling rings (2'; 2") is a plurality of gripping teeth (15'; 15"), preferably arranged in at least one row; and wherein the at least two coupling rings (2', 2") arranged on both sides in relation to the clamping sleeve can each be received in one of the collar bearings (3', 3") so that tensile forces acting in the assembled state on the pipe sections (R1; R2) are compensated to form an axially high tensile strength repair coupling, and so that the sealing area achieved through the clamping sleeve and the axial tensile strength achieved through the coupling rings (2'; 2") is spatially separated to prevent negative influencing of the impermeability of the sealing element; wherein a third axial extension (z) of a respective coupling ring (2', 2") is at a ratio of preferably 1 to 5 to 10, more preferably 2 to 4 to 10, most preferably around 3 to 10 in relation to a second axial extension (y) of the clamping sleeve.
