Claim:
1. A resin injection system for sealing a joint or breach in an electrical cable, comprising: a spacer material for application to the joint or breach, the spacer material being resiliently deformable and at least locally permeable to a fluid; a non-return valve, for positioning on the spacer material applied to the joint or breach; and a fluid resin for introduction through the valve into the spacer material applied to the joint or breach, wherein the non-return valve comprises: i. a valve housing which includes an outlet for a fluid flowing through the valve; and ii. a valve body which is held by the valve housing and is freely movable between a closed position, in which the outlet is substantially sealed or closed to fluid flow by the valve body, and an open position, in which the outlet is substantially open to fluid flow, wherein the valve housing comprises a flange member configured as a footing to support the valve on the spacer material of the resin injection system, and wherein the valve body is configured to seat against the flange member in the closed position and/or to project beyond the flange member in the open position.
