<p>The invention relates to an apparatus for connecting a bottle (11) containing a medicament to a syringe (5) the needle (6) of which is housed in a closed chamber (7) defined by the apparatus and from which the needle (6) can be made to emerge by sliding the separate constituent parts (1, 2, 3) of the apparatus along each other. To prevent the needle (6) emerging from said chamber (7) when no bottle (11) is housed in the appropriate seat provided in the apparatus, there extends from one of the parts (1, 2, 3) of the apparatus an elongated flexible appendix (12) having at least one protuberance (13) which projects into said seat and against which the bottle (11) presses when inserted into the seat, so bending the appendix (12) outwards. In front of the free end of the appendix (12) there is provided a stop tooth (14) projecting from that constituent part (3) of the apparatus which is mobile along the first stated part (1) and extends totally around said seat. When no bottle (11) is inserted into the seat in the apparatus it is impossible to move the various parts (1, 2, 3) of the apparatus along each other because the free end of the flexible appendix (12) makes contact with and halts against said stop tooth (14), to thus prevent the needle (6) emerging from said chamber (7).</p> |
