To provide a needle tip protector for indwelling needles, with a novel structure, capable of further improving safety, etc. than the conventional one.SOLUTION: A needle tip protector 10 for indwelling needles, includes a cylindrical peripheral wall 58, is externally mounted on a needle hub 22 of an indwelling needle 16, and moves to a needle tip 14 side to cover the needle tip 14 of the indwelling needle 16. Locking parts 74 and 74 locked to the needle hub 22 at a moving position to the needle tip 14 side of the indwelling needle 16 and blocking retraction of the indwelling needle 16 to a proximal side to prevent re-exposure of the needle tip 14, are formed inside covered by the cylindrical peripheral wall 58, where the locking parts 74 and 74 are integrally formed with the cylindrical peripheral wall 58.SELECTED DRAWING: Figure 3
