Small S-hook Clip, double ended Carabiner style

This clip is intended for light loads. To attach something to it such as a key - bend a leg out and slip it on. When a load is applied, the loops flex & the hooks engage like a monkey grip - that is until the plastic give it up and the hooks slip sided ways apart - down hill from there . . . .

A great little clip for things that need to be clipped & un-clipped to other things. Holds reasonably well, easy to open and reset, . . . .

Scale it to be larger if necessary.
