    a cap positioned between the sheath hub and the dilator hub, the cap possessing a through-hole;

    the dilator tube passing through the through-hole of the cap and passing through the through passage of the hemostatic valve;

    the cap being positioned in a first position in which an engaging member on the cap and the sheath hub are spaced from one another, the cap being axially movable in a distal direction to a second position in which the engaging member on the cap and the sheath hub engage one another to hold the cap at the second position; and
