Abstract
A unique retainer is disclosed having a plurality of resilient arms securing a tube within a housing bore. The arms include a radially inner section having a pair of circumferentially extending braces which increase the strength of the arms. The braces have axial ends which are bent radially outwardly and increase the strength of the arms, and also result in a more consistent, predictable buckling force for the retainer. Arm bends are formed between the arm radially inner section and a radially outer section. The axially outer bends of the braces are generally axially aligned with these arm bends, such that the bends provide a planer surface for positioning the retainer within the housing. Also, 'bumps' are defined at a radially inner face of the radially inner sections of the arms to create a high force resisting tube insertion. The bumps are at an angle relative to a central axis that is greater than the angle of the remainder of the radially inner section of the arms. Thus, the retainer arms may extend at a first angle which is relatively small relative to the axis and can provide a great force resisting tube removal, while the bumps are at the greater angle, and can provide a relatively great force resisting tube insertion.
