<p>A syringe is provided that comprises a plunger (10) which is adapted to be locked in place when it is fully compressed. The plunger comprises a frangible section (24) which has a breaking strength less than the holding strength of the locking structure. Thus, if an attempt is made to withdraw the plunger and reuse the syringe after the plunger has been fully compressed, the plunger will break, rather than withdrawing from the syringe barrel.</p> |
