<p>The device is particularly useful for laboratory equipment for locking a male member (10) in engagement with a female member (14). The device comprises a sleeve (23) having a threaded bore portion (24) enagagable with a threaded part (22) of the male member (10). The sleeve has a recessed bore portion (30) defining a first shoulder (38) between the portion (24) and recessed portion and a second shoulder (36) adjacent an end of the sleeve. The sleeve has a slot (32) to permit snap engagement of the sleeve on the female member, which has an outwardly projecting annular lip (18). The sleeve can be screwed up to engage the second shoulder (36) under the lip (18) to lock the members in engagement. The sleeve can be screwed down to urge the first shoulder (38) against the rim of the female member to break the seal between the interengaged members to facilitate their separation.</p> |
