Abstract

The invention provides a method of forming a connection to a cable duct, which method comprises: (a) clamping about an uncut region of the cable duct (D) a restraining device comprising a linked pair of longitudinally spaced apart restraining (2,2') elements; (b) cutting the cable duct at a location between the restraining elements; and (c) securing a connector (C) to one or both cut ends of the cut cable duct; wherein each restraining element is configured to grip one of the cut ends so as to restrain the two cut ends against relative longitudinal movement therebetween. Also provided is a restraining device for use in the method of the invention, wherein the restraining device comprises a pair of restraining elements and a linking element for linking the two restraining elements.
