A lock mechanism comprises a linear drive bar movable between two positions by a handle; movement of the drive bar prevented by actuation of a cylinder lock; the lug of the cylinder acting on a locking unit. The locking unit includes a linear locking element 62 engagable with the drive bar to retain the bar in position; a guide element (retainer) to guide linear movement of the locking element; and a detent mechanism 66 to retain the locking element in position. Guide formations such as guide rail 72, channel 74, are provide on the locking element 62 and retainer 64. The detent mechanism may be a spring biased ball bearing 82 engaging within recesses 80 in the locking element which may retain the locking element in the locked and unlocked positions. The guide element 64 may be fixedly housed within the housing by pegs 90 and prevents tampering of the locking element by manipulation tools.
