A leakproof joint construction for a pair of members disposed in abutting relation and method and apparatus for making the same are provided, the leakproof joint construction having part of one of the members deformed into an adjacent part of the other of the members so that the parts of the members are disposed completely beyond the plane of the outer surface of the other member while respectively being integrally interconnected to the remainder of the members by tubular portions of the members. The parts are interlocked together by an outward staking of the part of the one member into the tubular portion of the other member by a compaction of the parts, the parts and the tubular portions of the members respectively defining like polygonal configurations.
