ABSTRACT:
A key ring clip lock apparatus for holding the plunger of a gas pump handle in a positional mode for automatic pumping operation has a key holding portion for directly holding keys or the like thereon, including a resiliently deformable portion for permitting opening and closing of the key holding portion to receive and to remove such keys or the like, and a clip-like portion for grabbing part of the pump handle to hold the apparatus thereto with the plunger in a substantially compressed, valve-open position so as to allow hands-off gas pumping operation of an associated gas pump. In a preferred embodiment the apparatus is a formed rigid metal wire with first and second rigid lengths, one being concave curved with respect to the other, and a connecting length securing them in relatively fixed positions spaced apart a distance adequate to accommodate at least part of the plunger and pump handle with the plunger in an automatic pumping positional mode, and the key holding portion is formed of a rebent extension of the second rigid length providing a useful lever arm to facilitate placing and removing keys and to provide an enlarged effective surface to facilitate manual manipulation and use of the apparatus.
