ABSTRACT:
A tamper-proof and theft-proof electrical connector including a termination unit with a hexagonal front portion internally threaded to be fitted to an externally threaded output terminal of a distributing source. The unit has a rear portion smaller in diameter than the front portion. An annular groove is provided in the rear portion, and a cylindrical clip is retained in the groove. The clip has leaf spring tines which have ends that are spaced from but extend outwardly and toward the front portion. A locking shield is then provided which covers the entire length of the termination unit. The locking shield has an annular portion to fit between the tines and the front portion. The locking shield can be removed with a tool that depresses the tines.
