A locking device for keeping a window or sliding door from opening beyond a predetermined limit includes telescoping inner and outer members. A fastening mechanism selectively locks the inner member and the outer member. In one embodiment, the outer member has a first lateral side with a series of holes on one side spaced apart at a first distance and the second lateral side with a series of holes spaced apart at a second distance. The holes allow fine length adjustment of the locking device. The fastening mechanism is press-fit inside the inner member and includes a push pin to lock the inner member and outer member. The push pin is integrated on a c-shaped clip to spring-bias the push pin in place within the inner member. In another embodiment, the fastening mechanism extends from the inner member and rotation of the inner member locks enables the fastening mechanism to lock against the outer member.
