A relay housing comprising a cover plate which is inserted in a step-shaped recess of a housing rim. The rim portion of the plate has a reduced thickness so that there is formed a rim channel between the plate and the housing rim. The channel is in communication with fill-in cavities in the cover plate through which the channel is filled with a self-hardening or curable material. The fill-in cavities are formed as flat recesses adjoining the rim channel with wide openings, not connected among each other, that are at least twice as large as the width of the rim channel. The bottom of the channel slopes downwardly from said openings. This arrangement permits a quick sealing by use of only small amounts of sealing compound.
