An apparatus for securing a closable opening such as a door opening is disclosed. The apparatus has a metal bar (10) pivotally connected at one end to a door post (12) by means of a bolt (11). The other end of the bar (10) is releasably fastened to the opposite door post (15) by means of a housing attached to the door post (15) by a bolt (16), and fitted with a spring loaded pin (17) which fits through an aperture (13) in the end of the bar (10). The bar (10) may thus carry a tension loading when in use with its ends securely attached to the opposite door posts (12, 15), thereby providing a strong and visually secure means for securing the door opening. The use of flexible elongate members such as seat belt webbing is also disclosed, as is the use of the device in association with and electrical locking means. <IMAGE> |
