A needle safety device has a collar (4) and a housing (6) pivotally connected thereto. Cooperating locking members are provided at the collar and the respective lower sections of the housing so that, once the housing is pivoted to be in alignment with the collar, the locking members would coactingly mate with each other to thereby retain the housing to die collar. To ensure that the coacting locking members could not be sabotaged by the sidewalls of the housing being deliberately forced away from the collar, barriers (24a, 24b) in the form of guard flaps or arms are provided at the collar so as to prevent those sections of the sidewall that are susceptible to being forced away from the collar from being exposed. As an added benefit, the guard flaps could be used as an anchor to provide stabilization for the use of a hypodermic needle fitted with the safety needle device of the instant invention during a subcutaneous procedure to a patient.
