An infusion set adapted to be secured to a skin surface includes a fixed base member and a movable slide member. The fixed base member is connectable to the skin surface. The movable slide member has a needle or cannula connected thereto and is movable relative to the fixed base member. The movable slide member is movable from a first position in which the needle or cannula is not exposed externally of the fixed base member to a second position in which the needle or cannula is exposed externally of the fixed base member. A hub is fixedly connected to the movable member and has a slot extending rearwardly in a lower surface from a first end thereof. The needle or cannula is received in the slot. The movable slide member is locked to the fixed base member in the second position.
