ABSTRACT:
A security transfer device (1) for mounting on a side wall of a building such as a bank, for example, for transferring valuables between a vehicle and the building includes a duct (2) slidably mounted in a housing (3) secured in a wall (23) of the building and movable between a retracted stored position within the housing (3) and an extended in-use position projecting outwardly of the housing (3). A releasable ratchet mechanism (4) extends between the duct (2) and housing (3) . When engaged the ratchet mechanism only permits outward movement of the duct (2), thus preventing the duct (2) from being pushed back into the housing from outside the building. A lockable door (12) closes an inner end of the housing (3). The duct (2) is also closed at it's rear end (19) by a lockable security door (20).
