A wing assembly is secured to the body (101), and the wing assembly including first and second wings (103) extending laterally in opposite directions from said body (101). A hollow needle (104) is arranged in said passageway (102), such that it extends distally from said body (101). A shielding arm (105) is attached to the polymeric body (101), such that it is pivotable from an open position to a closed position, wherein a tip of the needle (104) is covered by the shielding arm (105) in the closed position while the needle tip is uncovered in the open position. |
