FIELD: metallurgy, namely constructions of contact joint "anode clamp-busbar" of self-firing anode of electrolyzer with lateral electric current supply. SUBSTANCE: apparatus including head of anode clamp with opening in its contact portion, busbar of anode outlet and wedge also includes pressure bolt with nuts and disc springs. There is slit in head of anode clamp; said slit connects opening of contact portion of head of anode clamp with one lateral face of head for mounting pressure bolt assembled with nuts, disc springs and busbar. EFFECT: enhanced quality, increased stability of contact joint, lowered labor consumption for mounting-demounting such joint. 2 dwg
