Abstract: A seal of the type includes a housing and a J- or U-shaped hasp, the housing having first and second openings to receive the legs of the hasp. The first opening communicating with a third opening of the housing to form a channel for a first leg of the hasp. A locking mechanism is provided within the housing which is biased to resist withdrawal of the first leg of the hasp through the first opening. The hasp being lockable within the housing such that it can only be removed by cutting of the first leg of the hasp. The legs of the hasp are substantially rigid and are connected together by a resilient hinge such that in a first, relaxed position the legs adopt a position in which they are not parallel, the legs being moveable to a second, parallel position against the resilient force of the hinge for insertion into the housing.

Abstract: A security seal has a housing and a hasp moveable relative to the housing in a first direction between a locked position and a unlocked position. The hasp, in the locked position, is lockable to the housing by a disposable seal. The housing has an opening to allow the insertion of the disposable seal in a second direction different from the first direction. The hasp includes a first locking element engageable, in the locked position, with a second, matching locking element of the disposable seal to prevent movement of the hasp in the first direction toward the unlocked position and withdrawal of the disposable seal in the second direction. The hasp is attached to the housing so as to be both slidable and pivotable relative to the housing.
