The invention relates to a window latch with a lockable bolt axially slideably mounted in a housing. The locking means for the bolt is a keyless combination lock incorporating rotatable slotted annular locking collars located in the bolt housing and disposed coaxially around the bolt. The bolt in the locked position is received in bolt receiving means, there being a pivotable latch on the bolt receiving means which has a surface having a co-operative relation with a tapered surface on the housing so that when the bolt is in the locked position the latch holds the bolt receiving means and housing securely together.
