A needle safety device has a collar and a housing 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 the 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 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.

Un dispositif de sécurité pour aiguille possède une collerette et un boîtier raccordé pivotant. Des éléments de verrouillage coopérants sont aménagés sur la collerette et les parties inférieures respectives du boîtier de manière à ce qu'une fois que l'on a fait pivoter le boîtier pour l'aligner sur la collerette, ces éléments s'interverrouillent de façon coopérative pour retenir le boîtier sur la collerette. Afin d'empêcher la destruction des éléments de verrouillage par les parois latérales du boîtier si quelqu'un essaie de les forcer à se détacher de la collerette, on a aménagé sur la collerette des barrières sous la forme de rabats ou de pattes de protection de manière à ne pas exposer les parties de la paroi latérale qui pourraient être forcées à se séparer de la collerette. Un avantage supplémentaire des rabats de protection consiste en ce qu'ils peuvent être utilisés comme un ancrage qui assure la stabilisation permettant d'utiliser une aiguille hypodermique équipée d'un dispositif de sécurité pour aiguille de la présente invention pendant une procédure d'administration sous-cutanée à un patient.
