Abstract: In a gas tight receptacle, particularly for an emergency respirator, a safety lock is disclosed which comprises an eyelet or slotway in a bottom and cover part of the receptacle. Both eyelets or slotways are engaged in a fixed manner by elastic tongues of a locking member. The locking member has a weakened portion in the area of the seal so that it can be broken to permit the full opening of the receptacle.
