Patent ID: 7448821

Claim:
An arrangement, comprising: a tubular element connectable to a body extending into the tubular element; and a tension ring adapted to embrace, by an inner surface, an outer wall at an end of the tubular element, the tension ring adapted to extend axially along the tubular element and adapted to apply a clamp force to the tubular element so that the tubular element acts via an inner wall of the tubular element on the body extending into the tubular element to clamp the tubular element on the body; wherein the tension ring includes a first axial section and a second axial section contiguous in an axial direction to the first axial section and is adapted to rest by only the first axial section of the inner surface against the outer wall of the tubular element and is adapted to exert a clamp action on the outer wall of the tubular element; wherein at the end, a wall of the tubular element on which the tension ring is to be positioned includes a smaller thickness than a contiguous axial region of the tubular element; wherein the first axial section is configured to face an end face of the end of the tubular element; wherein the second axial section is configured so that the inner surface of the tension ring does not rest against the outer wall of the tubular element in the second axial section; and wherein a distance from a center axis of the tubular element to the outer wall of the tubular element, in an area of the outer wall of the tubular element against which the first axial section is configured to rest, is larger than a distance from the center axis of the tubular element to the outer wall of the tubular element in an area embraced by the at least one second axial section.
