Abstract
This connection system has particular application to releasably securing a flexible elastic catheter to a rigid portal outlet stem received in the catheter lumen. The system includes a radial enlargement on the outlet stem and a retainer sleeve that slidably encircles the stem. The sleeve is slidable along the stem between a clamping position wherein it tightly engages around the stem enlargement and the segment of catheter encircling same at a circular contact surface and a release position wherein it is spaced from the catheter segment. The system assures a secure, fluid-tight connection of the catheter to the stem and provides strain relief for the catheter.
