Abstract

A closure for the outlet end of an ampoule having a neck with an outwardly extending annular projection (30), said closure comprising a holding cap (18;61) with a skirt (35;62) with interior protrusions (38) for engagement behind the annular projection (30) of the neck, which holding cap engages a disc shape part (31) to press it sealingly against the annular projection (30). A locking ring (20;64) on the outer side of the skirt (35;62) locks projections (38) in their engagement position behind the annular projection (30). Resilient fingers (37;65) and recesses (36;66) are provided on either the skirt or the locking ring, the recesses being positioned below the fingers so that the fingers may be pushed into the recesses when the locking ring is passed over the skirt. Either the skirt (35) or the locking ring (64), which part is not provided with the fingers and recesses, is provided with an edge over which the fingers may grip irreversibly when the locking ring is mounted in position on the skirt.
