ABSTRACT:
A sterile port cover which can be easily removed but is difficult to replace, and if replaced can be easily detected. A rigid port tube is sealably secured within a flexible plastic sleeve which extends beyond the end of the port tube. The sleeve is closed at this end and has a weakened section forming an intended fracture line. The sleeve is adapted to be separated at this fracture line and removed to expose the end of the port tube.
