Abstract: A pressure chamber in a vessel is closed by a cover which is recessed in the vessel in abutment with a shoulder thereof and retained therein by a detachable support assembly. A semitoroidal sealing member is received in an annular chamber formed by the cover, the support assembly and the inner wall of the vessel and the sealing member opens outwardly and one circumferential edge of the sealing member is welded to the cover and the other circumferential edge is welded to the inner wall of the vessel. The support assembly is constituted by a subdivided annular member partially received in a circumferential recess in the wall of the vessel and an annular inner locking member within the subdivided member and detachably secured to the cover.
