thereby to the female component 12 through the male component 14 via the support lugs 134 136 138 and 140 engaging the corresponding catches of the female component no stress is applied to the electrical contacts 70 and 72 hence the design of the lugs and catches of the male and female components is independent of the electrical contacts to thereby support any desired weight of the light fixture without interfering with the electrical contacts in this way the electrical contacts resiliently urge the clips upwardly to ensure continued electrical contact of the light fixture to the power source in incoming line 18 as shown in fig4 the male component 14 has extending outwardly of the stud portions a plate extremity 182 184 for supporting the two bolt fixture of fig5 and 6 via apertures 74 and 76 as discussed above when the unit is assembled the female component 12 is flush against the face of the finishing material for the wall or ceiling to complete the assembly and provide a flush mount of the light fixture and the cover plate 44 extends so as to cover the entire connector and fit flush with the wall or ceiling the male and female components of the coupling device are attached by means of the separate interengaging studs and catch portions the system has been designed for close tolerances to achieve a secure.
