Abstract
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® 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® 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.

Total Claims: 15
Claim 1
Independent Claim
147 words
Device for holding together a pair of mating electrical plugs which comprises at least one strap of fabric carrying a multiplicity of hooks on one face, the strap being devoid of hooks along a base area at one end, said strap being affixed by such base area to one side of a first one of said plugs with its hooked end extending beyond its end the hooks facing inwardly toward the plug to which it is fastened, a corresponding pad of fabric carrying a multiplicity of loops on only one side, said pad being affixed by its loopless side to the side of the second one of said plugs with its looped side facing outwardly toward the hooks of the strap, whereby when said plugs are mutually engaged said strap and said pad may be manually pressed together to lock said hooks and loops to each other.
Claim 2
Dependent Claim
147 words
Device for holding together a pair of mating electrical plugs which comprises at least one strap of fabric carrying a multiplicity of hooks on one face, the strap being devoid of hooks along a base area at one end, said strap being affixed by such base area to one side of a first one of said plugs with its hooked end extending beyond its end the hooks facing inwardly toward the plug to which it is fastened, a corresponding pad of fabric carrying a multiplicity of loops on only one side, said pad being affixed by its loopless side to the side of the second one of said plugs with its looped side facing outwardly toward the hooks of the strap, whereby when said plugs are mutually engaged said strap and said pad may be manually pressed together to lock said hooks and loops to each other.
