a movable slide member having a needle or cannula connected thereto, movable relative to said fixed base member, said movable slide member being movable from a first position in which said needle or cannula is not exposed externally of said fixed base member to a second position in which said needle or cannula is exposed externally of said fixed base member, said movable slide member being locked to said fixed base member in said second position; and
an inserter removably attachable to said infusion set, said inserter including a movable inserter member and a fixed inserter member,wherein when said inserter moves said movable slide member from said first position to said second position, said movable inserter member moves to engage said fixed base member and prevent premature withdrawal of said movable inserter member from said fixed base member, the movement of said inserter being in a direction different from the movement of said needle or cannula between said first and second positions.
