Protective sheath for winged needles

In a needle set of the type including a length of tube having a hollow needle at one end, a pair of outwardly projecting flexible wings adjacent the end of the tube with the needle, and a protective sheath slidably disposed on the tube and adapted to be slid over the needle to cover the needle after use, said sheath comprising a hollow, generally tubular shaped body having a forward end oriented toward the needle and a rearward end oriented away from the needle, said body having at least one longitudinally extending slot commencing at the forward end thereof and extending towards the rearward end for slidably receiving the wings therein to allow at least part of said sheath to be slid past the wings to cover the needle, the improvement comprising:

• a guard at the rearward end of said sheath extending radially outwardly from said sheath and at least partially annularly around said sheath so as to prevent a user's hand which has grasped the rearward end of the sheath in order to pull the tube therethrough from sliding towards the forward end of the sheath.
