Patent ID: 7509726

Claim:
A method for securing a tube element ( 21 ) to an inner part ( 18 ) by plastic deformation, the tube element ( 21 ) having a closed cylindrical wall and, prior to securing the tube element ( 21 ) to the inner part ( 18 ), the wall having at least one recess ( 5 ), comprising: placing the tube element ( 21 ) onto the inner part ( 18 ); deforming the tube element ( 21 ) in the region of the at least one recess ( 5 ) with a tool by exerting a force on the tube element ( 21 ) in a deforming direction transversely to the diameter of the tube element, whereby the at least one recess is contracted transversely to the deforming direction and the diameter of the tube element is reduced; and continuing the deformation of the tube element ( 21 ) until the tube element is pressed radially onto the inner part ( 18 ).
