ABSTRACT:
An adaptor for electrical junction box comprises: a split sleeve insertable through a wall opening of a box wall of a junction box, and coupled on a cable connector; a plurality of resilient chucking members each integrally formed on the sleeve and sloping rearwardly upwardly from the sleeve to be resiliently compressibly engaged with the wall opening; each chucking member having a plurality of ratchet teeth gradationally formed on the chucking member, whereby upon a forward insertion of the adaptor into the wall opening of the junction box, the split sleeve will be resiliently fastened on the cable connector, and the wall opening will be firmly engaged with the ratchet teeth to stably lock the adaptor and the cable connector on the box wall to prevent a backlash movement of the adaptor and the cable connector.
