Claims
- 1. A security device for use with a hasp device having a hasp staple opening, said security device comprising:
- a first shackle element including a front planar surface and a back and a second shackle element including a front planar surface and a back, each of said shackle elements being configured to have a hook-shaped free end, an intermediate body portion and a second end distal from said free end, said second ends each having a length, at least one of said first and second shackle elements being moveable with respect to one another between an open position at which said front planar surfaces lie askew relative to one another creating a space between said front planar surfaces which is adapted to allow the free ends to be inserted into or removed from the hasp staple opening of the hasp device and a closed position at which said front planar surfaces lie relative to one another to substantially eliminate said space between said front planar surfaces; in said closed position, the free end and the body portion of said front planar surface of said first shackle element overlie a portion of the free end and the body portion of said front planar surface of said second shackle element, said first and second shackle elements being connected to one another along a hinge axis which extends substantially the entire length of said second ends, said first and second shackle elements being moveable such that said first and second shackle elements are rotated from said closed position to said open position only by rotating at least one of said front planar surfaces of said shackle elements about said hinge axis in an opening direction which is away from said front planar surface of the other shackle element, there being no movement of said at least one shackle element in any other direction other than said opening direction when at least one said shackle element is moved from said closed position to said open position; and
- a security seal associated with both of said first and second shackle elements for selectively securing said first and second shackle elements in said closed position to thereby prevent movement of said shackle elements, wherein one of said intermediate body portions carries a hasp projection and the other of said intermediate body portions includes an opening through which said hasp protection extends at least when said shackle elements are in said closed position such that said security seal can be inserted through said hasp projection to thereby prevent movement of such shackle elements away from one another.
- 2. The security device in claim 1, wherein said security seal is a one-time use seal.
- 3. The security device is claim 1, wherein each of said free ends of said shackle elements is at least partially tapered in at least one dimension.
