Abstract
A catch or lock with a cam (3) rotatable to move one or two resilient latching arms (20) at the end of which may be latching means (25) engageable on a hasp (4) to catch or lock an article. The cam (3) or casing (1) has a follower (18) which acts in a groove (15) with a ramped bottom dividing the groove into two portions and preventing the cam from being rotated from the second back to the first portion. When the cam is in a first position (X) with the follower in the first portion the latching means are held open and are inoperative for latching. The key is then inserted to move the cam so the follower is in the second portion, the cam being movable between positions (Y) and (Z) in which the latching means open and close respectively, and the key is removable in position (Z).
