The invention concerns a safety device for monitoring heat for connections in electrical installations. Said device comprises a first connecting element (14) in thermal relationship with an electrical connection to be monitored. A second element (35) is also designed to be connected to the ground of the general electric installations. Electrical connecting means (21) connect said two elements and can adopt two states, one an insulating state in normal operating conditions and the other an interrupting state wherein there is contact and hence earthing of the first element with the second when a critical temperature is reached.
