An improved electrolytic condenser comprising a cylindrical housing and a lid having an aperture, and a securing ring fitted into the opening of the housing by means of ultrasonic welding process or threaded engagement. In case of an inadmissibly high gas pressure in the condenser, through the aperture of the lid the excess gas will be discharged, thus the condenser being rendered explosion-proof and also the assembling process being shortened by the provision of the securing ring.
