A restrictor for a window or a door
A restrictor for a window or a door comprises a first connector (10) adapted to be secured to a frame or sash of the window or door and a second connector (3) adapted to be secured to the other of the frame or sash. A cable or link (6) is secured at one end to the second connector (3) and has a spigot (11) secured to its other end. A lock (13) is housed within the first connector (10) and defines a channel (12) that receives the spigot (11). The lock (13) comprises a movable locking member (19) that in a first position engages the spigot (11) to lock the spigot (11) within the channel (12) and that is movable into a second position to unlock the spigot (11) allowing its withdrawal from the channel (12). The movable locking member (19) is biased into its first position and moved into its second position against the force of the bias (26) by the spigot (11) on its insertion into the channel (12). Movement of the spigot (11) further into the channel (12) releases the locking member (19) to return to its first position under the influence of its bias (26) wherein it engages the spigot (11) to secure it in the channel (12) of the lock (13). Hence, the restrictor of the invention may always be deployed to restrict window or door opening as no key is required to lock the cable to the first connector via the spigot.
