Claim 1

An intravenous infusion set comprising: a hypodermic needle; a length of flexible tubing being connected to one end of the needle for delivering an infusant liquid to the needle; a second end of needle carrying a sharp tip, the second end of needle being housed inside a plastic material cannular sleeve, the needle being axially slidable relative to the sleeve between a first position, in which the sharp tip of the needle projects beyond the sleeve, and a second position in which the sharp tip of the needle is retracted and is located entirely within the sleeve; a first body moulding connected to and moveable with the needle; a second body moulding connected to the sleeve, the second body moulding being slidable relative to the needle whereby second body moulding is moveable in an axial direction toward and away from the first body moulding; a bridge integrally formed with one of the first and the second body mouldings, and the bridge projecting in an overlying relationship with respect to the other one of the first and the second body mouldings; and transversely extending wing-like strips integrally formed with the other one of the first and the second body mouldings, the wing-like strips being foldable toward one another and being positioned, when so folded, to clamp the bridge therebetween once the first body moulding has sufficiently moved axially toward the second body moulding so that the wing-like strips, when folded toward one another, are able to hold manually the first body moulding and second body moulding in a juxtaposed relationship once the needle is in the first position, and thereafter the wing-like strips, during use of the infusion set, being moveable to lie flat against skin of a patient to facilitate fastening of the infusion set to the skin of the patient.
