The window fastener comprises a base part 11 and a handle part 12 having a lug for engaging in the associated window frame. A key-operated locking mechanism 15 is provided to lock the handle part 12 to the base part 11 in the engaged position. The mechanism 15 comprises a locking pin 20 mounted within a bore 16 by means of a body 21, which has a cam surface 27 for engaging a cam follower 28. Rotation of the body by a key causes axial movement of the body and hence the locking pin 20.
