ABSTRACT:
A trip-wire guiding device for a protective fence is described including an elongated member attachable to ground-anchoring means intermediate the fence poles and formed with a plurality of openings through which the tensioned trip-wire are passed for maintaining them in parallel space relationship. Each trip-wire is insertable into the opening via a passageway extending from the opening to the edge of the member. A common locking member is received in a channel extending longitudinally through the elongated member aligned with and passing through the passageways, the common locking member being effective to lock the trip-wires in their respective opening against removal through the passageways, but permits their longitudinal movement, such as to cause the detector means to be actuated upon a change in tension in the trip-wires, but to preclude disabling the detector means by merely fastening the tensioned trip-wires to the wire-guiding member or to the common locking member fixed thereto.
In several described embodiments the elongated trip-wire guiding member is made of sheet metal, and in a further described embodiment it comprises an open spiral rod.
