Device for connecting a high-pressure line to an accumulator tank

A device for connecting a high-pressure line to a cylindrical accumulator tank, the device comprising:

• a fastener fastened to the high-pressure line,
• a connector having a first part with a first inside wall surface which defines a first hole for accommodating and fastening a portion of the cylindrical accumulator tank, the connector having a second protruding part extending outward from the cylindrical tank, the protruding part having a second internal surface, which defines a second hole extending outward from the tank for accommodating and fastening an end of the high-pressure line,
• a joining device operable to form a connection between the fastener and the connector,
• a first contact surface of the high-pressure line operable to engage a second contact surface of the accumulator tank,
• in an axial direction relative to the cylindrical accumulator tank, the first inside wall surface of the connector has a shape that enables relative pivoting movements between the connector and the accumulator tank when they are joined and the first and second contact surfaces are brought towards one another by the fastener acting on the connector, the first inside wall surface including a first region situated at a minimum perpendicular distance from a first central axis which extends in an axial direction through the first hole, and a second region situated at some greater perpendicular distance from the first central axis.
