摘要

The door or window closure retention device (2) has a closure plate (22) on a fixed frame or door or window panel and a closure device on a panel or frame. The closure device has a locking element (3) that interacts with the closure plate for locking and unlocking the panel. The closure device or lock (21) preferably has a lock catch that interacts with the closure plate in the closed position to lock and unlock the panel and is forced into the locking position by a spring device. The closure device can have two energy storage devices, one for actuating the locking element in the locking position and one in the unlocked position, or a common device for both functions.
