Claim:
1. A safety needle assembly comprising: a needle hub comprising a distally protruding end having a proximal end of a needle, which comprises a shaft with a needle tip and a diametrical enlargement proximal of the needle tip, attached thereto; a displaceable protective member for the needle tip, the protective member disposed on the shaft of the needle and having a proximal wall with an opening defining an engaging portion that engages the diametrical enlargement of the needle shaft to prevent the protective member from being displaced beyond the needle tip in a protective position; a tube having a tube body having a proximal tube end, a distal tube end, and a center section surrounding the protective member; said tube body has a heat activated locally reduced diameter defining a reduced section for confining the protective member within the center section so that said protective member is prevented from displacing out of the proximal tube end of the tube but is movable relative to the tube; and wherein an opening at the proximal tube end is larger than an outside dimension of the distally protruding end of the needle hub.
