ABSTRACT OF THE DISCLOSURE Coupling device for coupling releasably elec- trical fixture to electrical outlet adjacent building surface. Device has female assembly connected to elec- trical outlet box and power, the assembly having three female supporting lugs with engagement means. Respective electrical contacts are secured adjacent each lug and spaced from lug to provide gap between the lug and con- tact. Male assembly is connected to fixture and has three complementary male supporting lugs with engagement means complementary to the respective engagement means of female lug. Each male lug has contact extending along upper surface thereof to fit between female lug and respective contact. When male assembly is inserted into the female assembly and rotated relative thereto, engage- ment means of each lug engage complementary engagement means of opposite lug and respective contacts are forced into and maintain engagement so as to conduct electricity. Engagement means essentially prevent accidental rotation leading to disconnection, and female lugs shield live contact in disconnected fixture, thus reducing electrical shock hazard.
