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. The housing may be formed of a main body and a cover, the cover being sealed onto the body part, the cover having at least one protrusion which engages in a corresponding recess within the body part, and the protrusion having an aperture therethrough which in use receives one leg of the hasp.
