ABSTRACT:
A flame-proof cable gland for use with an unarmored electrical cable having a sheath providing a tensile strength and wherein a flame-proofing seal and a clamping ring are provided for co-operation with the outer surface of an electrical cable passing therethrough. The hardnesses of the flame-proofing seal and the clamping ring are selected so that, upon axial compression of both of them to cause them to bulge into contact with the outer sheath of an electrical cable, the flame-proofing seal is rendered operative first followed by the clamping ring.
