A stay for restricting the opening of a pivoted vent such as a window has a mounting plate 1 for attachment to a frame, a C-section track 10 for attachment to the vent, a slider 8 and a pivot arm 7 having a locking pin 5. The locking pin 5 is received in an opening 11 in the mounting plate 1 and is releasably secured therein by a spring clip 2 that engages in a groove 5a in the pin 5. A separate tool 6 is used to open the legs of the spring clip 2 to allow the pin 5 to be released. |
