A needle assembly includes a cannula having a lumen therethrough along its longitudinal axis and a hub having a distal end, a proximal end and a passageway therethrough defining a hub longitudinal axis. The cannula is positioned partially within the hub projecting outwardly from the distal end so that the lumen and the passageway are in fluid communication. The proximal end of the hub is adapted to engage and become in fluid communication with the fluid transfer apparatus. A first portion of the passageway at the distal end of the hub contains a quantity of adhesive which contacts the cannula for preventing removal of the cannula from the hub. A second portion of the passageway, adjacent to the first portion, contains a portion of the cannula for limiting angular misalignment between the cannula longitudinal axis and the hub longitudinal axis and for limiting the length of the cannula in the passageway.
