Patent ID: 7719421

Claim:
A security system comprising: a security strap having a head and an elongate tail; and a security device comprising: a housing having two sides opposite one another and further comprising a first passageway and a second passageway defined therethrough and having a first engagement surface which projects into the first passageway and second engagement surface which projects into the second passageway; and an elongate body extending from the housing to an end adapted to be inserted through the first passageway at one side wherein, in use, following operative insertion of the end of the body into the first passageway, the first engagement surface engages the end to prevent retraction of the end from the first passageway; the body, when prevented from retraction from the first passage way is bisected to permit the severed end of the body to be pulled completely through and drawn from the first passageway at the second side; the elongate tail is adapted to be inserted through the second passageway at the second side and then through the first passageway at the first side and engaged to prevent retraction, respectively, by the second engagement surface and the first engagement surface; the strap is prevented from being drawn completely though the second passageway by interference between the head and the housing such that, when the elongate tail is inserted through the second passageway and then through the first passageway, the housing securely links longitudinally spaced-apart portions of the strap.
