Claims19
A tamper indicating security seal comprising a housing, a strap member extending from said housing, said strap member including at least two locking elements extending outwardly therefrom in spaced relationship with respect to one another, an inlet opening into said housing of a size to receive said strap member, a first locking means within said housing including a plurality of locking fingers having inwardly extending portions defining a restricted passageway, said inwardly extending portions of said locking fingers of said first locking means being configured to abut a first one of said locking elements of said strap member when said strap member is inserted within said housing to thereby resist the withdrawal of said strap member from said housing, a second locking means movably mounted within said housing and having a base defining an opening therethrough for selectively receiving said strap member and a plurality of spaced locking fingers having inwardly extending portions for selectively engaging a second one of said locking elements of said strap member when said strap member is inserted within said housing, said base portion of said second locking means being movable into engagement with said locking fingers of said first locking means when a force is exerted in a direction to withdraw said strap member from said housing to thereby urge said locking fingers of said first locking means toward said strap means.
A tamper indicating security seal comprising a housing and a strap member extending outwardly relative to said housing to an outer end portion, an inlet opening into said housing of a size to selectively receive said strap member therethrough, said housing having first, second and third bores therein in general axial alignment with said inlet opening, a first inwardly extending shoulder between said first and second bores and a second inwardly extending shoulder between said second and third bores, a first locking cage means having a base portion fixedly mounted within said first bore and having a plurality of locking fingers extending into said second bore, said locking fingers of said first locking cage means including portions for engaging said locking elements of said strap member when said strap member is inserted therebetween so as to prevent the withdrawal of said strap member from said housing, a second locking cage means movable within said second bore from a first position spaced from said first locking cage means to a second position in engagement with said locking fingers of said first locking cage means, said second locking cage means including a base portion and a plurality of locking fingers extending outwardly from said base portion into said third bore, said locking fingers of said second locking cage means including portions for engaging said locking elements of said strap member when said strap is inserted through said second locking cage means, and said portions for engaging said locking elements of said strap member of said locking fingers of both said first and second locking cage means simultaneously engaging spaced locking elements of said strap member when said second locking cage means is in said second position.
A tamper indicating security seal comprising a housing and a strap member extending outwardly relative to said housing to an outer end portion, an inlet opening into said housing of a size to selectively receive said strap member therethrough, a first locking cage means having a base portion fixedly mounted within said housing and having a plurality of locking fingers, said locking fingers of said first locking cage means including portions for engaging said locking elements of said strap member when said strap member is inserted therebetween so as to prevent the withdrawal of said strap member from said housing, a second locking cage means movable within said housing from a first position spaced from said first locking cage means to a second position in engagement with said locking fingers of said first locking cage means, said second locking cage means including a base portion and a plurality of locking fingers extending outwardly from said base portion, said locking fingers of said second locking cage means including portions for engaging said locking elements of said strap member when said strap is inserted through said second locking cage means, and said portions for engaging said locking elements of said strap member of said locking fingers of both said first and second locking cage means simultaneously engaging spaced locking elements of said strap member when said second locking cage means is in said second position.
