Keck clips are used to hold ground glass joints and downstems together. Keck Clips are designed to securely hold your glass joints securely together preventing accidental detachment for your water pipe or bong, dab rig or mini tube.  If you are looking for a metal KECK clip take a look at our Sick Clips designed by a glassblower for glass.  These metal KECK clips or SICK clips really make your rig look good compared to a plastic clip.  The plastic KECK clips are really great for someone wanting to save money and have a solid clip.
