Abstract: An artefact is provided for use in cases where two bodies are to be connected together by load limiting means.The artefact comprises one portion adapted to be connected rigidly with one of the bodies and a second portion to be associated with the other body and connected in pressure-sensitive or tension-sensitive relationship with the first portion by a connection which incorporates at least one load limiting means which consists of at least two members, one of which is adapted to deform when the load between the two portions exceeds a predetermined value so as to permit of relative movement between the two members.Such artefact is useful in connection with the protection of pressure vessels from excessive build-up of internal pressure since the artefact may be used in securing a blow-off panel to the vessel.
