Abstract: Device for releasably holding together the male and female plugs of a power tool and an extension cord. A strap of interlocking "hook" material, e.g. Velcro.RTM. heavy-duty hook-type fastener, is adhered to either side of the male plug, the straps extending longitudinally past the face of the plug approximately two inches. A pad of interlocking "loop" material, e.g. Velcro.RTM. heavy-duty loop-type fastener, is adhered to either side of the female plug so as to face the straps when the plugs are engaged, whereupon the straps may be pressed into interlocking engagement with the pads. The thus engaged two plugs cannot easily be accidentally pulled apart, however, they are readily detached by the user when he wishes to disconnect them.
