A needle protective housing is fitted to the neck of a medicament container, for example a glass vial, that has a circumferential notch formed at a proximal portion of the neck. The needle protective device has a needle protective housing pivotally connected to a cup-shaped collar. The collar has a base that is formed by a plurality of coplanar extensions, that in turn form an aperture that allows the base to be press-fitted onto the neck of the vial. The extensions are each separated by a space, so that the extensions would give way when the collar is slidedly fitted along the length of the neck of the vial, until the extensions reach the notch at the proximal end of the neck of the vial where the extensions return to the original shape to thereby couple the collar to the vial.

Selon la présente invention, on ajuste une gaine de protection d'aiguille sur le col d'un contenant pour médicament, par exemple une fiole de verre, qui est muni d'une entaille circonférentielle formée dans une partie proximale du col. Le dispositif de protection d'aiguille de l'invention comporte une gaine de protection d'aiguille reliée pivotante à une bague en forme de godet. La bague comprend une base qui est formée d'une pluralité d'extensions coplanaires, qui forment à leur tour une ouverture qui permet d'ajuster la base sur le col de la fiole. Les extensions précitées sont chacune séparées par un espace, de sorte que les extensions cèdent lorsque la bague est ajustée coulissante sur la longueur du col de la fiole, jusqu'à ce que les extensions atteignent l'entaille formée dans l'extrémité proximale du col de la fiole, où les extensions reprennent alors leur forme originale afin de coupler la bague à la fiole.
