ABSTRACT:
A tamper proof all plastic one piece security seal comprising a shackle or securing strap and retainer in which the retainer comprises a body having a keeper portion, defining a latching cavity, and a flange portion integral with one side of the keeper portion and also integral with one end of the shackle or securing strap. The other end of the shackle or strap is formed to define a rectilinear latching segment that has elastic memory, and is formed to define recesses spaced apart longitudinally thereof for free fitting relation with correspondingly located lugs formed in the latching cavity when the shackle latching segment is in its locked position. The latching cavity lugs and the latching segment recesses are oriented to require force fitting or feeding of the latching segment within the latching cavity such that bending distortion of the latching segment, laterally of same, will be necessary to bring the latching segment recesses into registry with the latching cavity lugs, whereupon the elastic memory of the latching segment will restore same to its rectilinear unstressed relation that locks the latching segment permanently within the latching cavity. The shackle or strap latching segment includes flanges for masking the latching cavity against violation when the seal is in its locked relation, and a frangible connection that integrally connects the latching segment as part of the shackle provides for ready breakage of the shackle to evidence tampering.
