A quick replacement, slack take-up electric cord for lamps, clocks, radios, etc, comprising a length of two-conductor lamp cord coiled and permanently set in a helix, one end of the lamp cord having a conventional two-prong electric plug for insertion in a wall receptacle. The other end of the cord has a special elongate receptacle made with a recess at the end opposite to the entrance of the cord. The receptacle has a push-button switch and a flat base for support on a table surface. Within the receptacle are two metal connector pieces having sharp prongs located at the inner end of the recess. The recess is oblong in cross sectional configuration to receive a freshly cut end portion of the original electric cord from the appliance, where it has been cut close to the appliance. The receptacle also has a manually operable lever to force the said cut end of the appliance cord laterally against the prongs so as to make electrical connection thereto. Replacement of an old cord involves merely cutting the cord an inch or so from the appliance, inserting the cut cord end deeply in the receptacle recess and then operating the lever to impale the cord on the sharp prongs. The plug of the replacement cord is then inserted in the wall receptacle. The receptacle switch will now be conveniently accessible to switch the appliance on and off.
