Safes.

摘要

A safe has a chamber (12) with an access opening. A closure (15) can be located in the opening so that peripheral grooves (17,21) around the opening and closure (15) respectively are aligned. A ring (18) is captive in the groove (17) around the access opening and is displaceable by a sliding member (22) in the closure (15) to a position in which the ring (18) engages both grooves (17,21) over approximately half of their peripheries, to lock the closure (15) in position.
