A window restrictor 10 has a first arm 20 pivoted to a frame mount 12 and a second arm 24 pivoted to window mount 14; first and second arms pivotally coupled 28 to rotate between folded (closed) position and an unfolded position approximately 180 degrees and pivoting further preferably beyond 180 to 190 degrees providing an over-centre hold open position. The restrictor permits limited opening of the window, providing child safe window opening. The first arm may include a wall element 32 as an upstanding lip against which the second arm 24 may abut providing a stop surface to limit rotation; the wall 32 may include an angled stop (30) with and end 38 abutting edge 36 of the second arm. A releasable locking mechanism may permit un-coupling/release of the first arm permitting unrestricted complete opening of a window. The first arm may include a peg received in recess and secured by the locking mechanism release by a key. One of the arms may include a projection to be received by a recess in the other arm providing a detent retaining means.
