Abstract

A lock assembly comprising: a lock housing 14 within which is mounted a shaft 18 having at a key head portion 19 with a key receiving aperture at one end and a latch 24 mounted to the shaft at the other end moveable between a locking portion and a unlocking position and a biaser to bias the shaft in the unlocked position; a key cover 12 at the key end of the housing having an aperture 16 wherein in the unlocked position of the shaft the key head portion is at least partially obscured/misaligned by the key cover, thus preventing removal of a key/tool 30 from the lock in the unlocked position. The housing may have a cutout portion 15 with edges 17 preventing rotation of the shaft/latch, preferably the shaft requires sliding/axial movement prior to rotation to unlock, the biaser may be a helical spring resisting compressing and axial displacement of the shaft away from the unlocked position and may also be a torsion spring resisting rotation. The lock may be used in a manhole cover.
