摘要

The device (1) to prevent unintentional movements of surfaces (17, 18) which are movable towards each other essentially comprises a cylindrical casing (2) with crosspiece heads (5) connected to said casing and extending in a transverse direction and a safety mechanism (3) within said casing for a screw (4) capable of being retracted into and extended from said casing which screw is connectable via a T-shaped crosspiece to a second surface part.
