A device and method are provided for sealing off an explosive charge compartment in a shell of the type in which the shell includes a shell case at its forward region and an element which is inserted into said shell case to cover an explosive charge and is provided with an outer annular abutment surface abutting against the inner contour of the shell case. The device includes a strand of sealant compound which is applied at least along an edge of the upper end portion of the element covering the explosive charge and a radially expendable ring which is forced by radial flaring against the sealant compound to straddle at least a joint between the edge of the upper end portion of the covering element and the inner contour of the shell case to accurately follow inner contours of the element and the shell case.
