ABSTRACT:
An injection site is provided which is molded inside out with inwardly extending rings. The rings have a smaller internal diameter than the external diameter of the tubular member to which the injection site is to be connected. The injection site has a central portion for receiving a needle therethrough, and a first, cylindrical portion which is extended into the tubular member. After such insertion, the portion with the attached rings is folded back onto the tubular member. The rings become positioned on the outside of the assembly and are in the compressed state squeezing tightly against the tubular member.
