Abstract
Abstract A shackle seal housing has a separate plug that is snugly received in its entirety within one end of the housing, the housing having an inwardly extending circumferential ridge and the plug having a groove in its outer wall which receives the ridge when the plug is seated. The inner end of the plug has a cavity which snugly receives the shackle end thereby preventing inward compression of the plug when it is seated within the housing. The housing may have a non-circular configuration, to prevent twisting of the shackle within the housing. The shackle strap may have a variable width border provided by an opening to permit selection of its breaking strength.
