  • an adaptor having a tubular body defined between a forward end and a rear end, said forward end being configured to engage a hub of the catheter and said rear end being configured to receive an end of the fluid supply tube, said adaptor body for defining a longitudinal axis;

    a support arm cantilevered radially outwardly from said adaptor;

    a clip support element mounted on said support arm, said clip support element having an elongated parallelepiped shape extending generally parallel to said longitudinal axis, said clip support element being mounted on an outer end of said support arm at a central section of said clip support element, the connection between said support arm, said adaptor body and said clip support element permitting pivoting movement of said clip support element about said adaptor body such that depressing a rear end of said clip support element toward said adaptor body moves a forward end of said clip support element away from said adaptor body;

    a clip comprising a forward latch configured to engage the hub, said clip slidably connecting with said support arm to move in a direction parallel to said longitudinal axis of said adaptor, said clip pivotably connecting to said adaptor to move said forward latch radially outwardly away from said forward end of said adaptor; and
