Abstract: A method of making fast setting permanently reinforced splice joints between a cable sheath and a sleeve which includes preparing a mixture of resin and filler additives which shrink upon curing and adding at the time of use a catalyst with a pigment color therein to indicate proper mixing. Resilient bands of rubber-like adhesive material are applied to the ends of the cable sheath to be joined and the self-curing resin is applied over the cable ends, the resilient band and the sleeve to be joined. The resin, when cured, shrinks to form a novel reinforced sealed splice joint.
