Abstract: A gate latch comprises a tubular support and a latch member having a shaft portion mounted within the tubular support for rotation therein and a latch portion, extending axially outwardly from the shaft portion, having at least one peripheral projection extending axially outwardly from the shaft portion. Spacing defined by the at least one projection is such as to permit entry therein of a complemental gate locking bar extending from a complemental gate. The locking bar has a locking element at its free end to engage within the spacing defined by the at least one projection in order to lock the gate relative to the tubular support. A combination of the gate latch with the complemental gate locking bar and gate is also disclosed.
