Tamper indicator assembly for valves and like devices

A device for providing an indication of tampering with a valve having a valve base, which comprises:

• an unperforated hollow cylindrical enclosure completely surrounding and enclosing said valve, said enclosure having an open end to receive said valve and a closed end to prevent access to said valve, said enclosure provided with aligned elongated slots proximate said open end;
• a flat locking bar for passing through said aligned slots proximate said valve base for engaging a portion of said valve to prevent removal of said enclosure from said valve, said locking bar having a first end portion and a body portion disposed through one of said aligned openings, said first end portion oriented substantially perpendicular to said body portion to prevent said first end from passing through said one of said aligned slots, said locking bar provided with an aperture proximate a second end extending exterior to a second of said aligned openings;
• and
• a seal member for passing through said aperture in said locking bar when said locking bar is passed through said aligned slots to prevent removal of said locking bar, said seal member requiring destruction thereof if removed from said aperture to thereby indicate tampering with said valve.

A device for providing an indication of tampering with a valve having a valve base, which comprises:

• an unperforated hollow cylindrical polyvinyl chloride enclosure formed from a cylindrical wall member and a polyvinyl chloride end wall cemented to said wall member whereby said enclosure has an open end to accept said valve and a closed end to prevent access to said valve, said wall member provided with aligned elongated slots proximate said open end of said enclosure;
• a flat steel locking bar for passing through said elongated slots proximate said valve base for engaging a portion of said valve to prevent removal of said enclosure from said valve, said locking bar having a first end portion and a body portion disposed through one of said aligned openings, said first end portion oriented substantially perpendicular to said body portion to prevent said first end from passing through said one of said aligned slots, said locking bar provided with an aperture proximate a second end extending exterior to a second of said aligned openings;
• and
• a seal member for passing through said aperture in said locking bar when said locking bar is passed through said aligned slots to prevent removal of said locking bar, said seal member requiring destruction thereof if removed from said aperture to thereby indicate tampering with said valve.
