1. A catheterization system comprising:

  • a catheter including an adaptor with a radially extending member that projects from said adaptor; and

    a retainer including first and second channel portions which extend about a longitudinal axis, each channel portion generally having a truncated cross-sectional shape with an opening along said longitudinal axis, and the cross section of at least one of the first and second channel portions tapering along its length, each channel portion having an upper opening of a width that is smaller than a diameter size of the adaptor and each channel portion being sized to surround at least a portion of the adaptor through an arc of greater than 180°

    about said longitudinal axis and at least one of the channel portions having walls which deflect outwardly as the adaptor is inserted through the opening and move inwardly toward their undeflected position once the adaptor is within the channel portion, and at least one lateral slot that extends generally perpendicular to said longitudinal axis and lies between said first and second channel portions, said slot having a longitudinal length so dimensioned to substantially equal the thickness of the radially extending member of said adaptor and to be less than the combined longitudinal lengths of said first and second channel portions to provide lateral stability of the adaptor within the retainer with the radially extending member positioned within said lateral slot.
