ABSTRACT:
A pump assembly used in conjunction with a fluid delivery set is disclosed which includes a tube slot into which the outlet tube of the fluid delivery set is intended to be mounted. The invention includes a retention member which is pivotally attached to the pump adjacent the point at which the outlet tube exits the tube slot of the pump assembly. The retention member includes a pivoting flat elongate arm which is secured to the pump by a pin and designed to rotate from a first position wherein the tube can be placed into the tube slot, and a second position wherein the tube is secured in the tube slot by the arm. The arm also has formed thereon a tab member which includes a tapered guide edge for ensuring that the tubing is forced into a secured position within the tube slot when the arm is pivoted thereover.
