ABSTRACT:
A unitary molded injection site comprising a central, needle-receiving portion and a skirt portion may be assembled onto a support tube by temporarily convoluting the skirt portion about the central portion to expose its inner surface; bringing the end of the support tube adjacent to the inner surface; and bringing the skirt portion back toward its original, unstressed configuration, to surround the end portion of the tube in telescoping relation. An advantage of this is that the injection site is positioned on the support tube in relatively unstressed condition. Furthermore, the skirt portion may define on its inner surface a plurality of sealing rings adapted to sealingly bear against the support tube.
