A needle tip spring protector for a needle having a proximal end, a distal end, and a shaft extending therebetween. The needle tip spring protector includes a spring that circumferentially surrounds a portion of the needle shaft and is restrained in a state wherein its inner diameter is large enough to allow the shaft to move freely within the spring. When the needle is moved to a position in which its distal end is at least partly within the spring, at least one of the ends of the spring releases from restraint such that the spring automatically returns to a state in which its inner diameter is sized so as to grippingly engage the shaft of the needle. Thus, after activation, the spring securely surrounds the distal end of the needle to protect healthcare workers and others from accidental contact with the needle's distal end. When used in conjunction with a catheter assembly, the needle tip spring protector may passively release from the catheter hub after the spring is automatically activated.
