A joint clamp – also called a Keck clip – is a small plastic or metal clip that holds two ground glass parts together. It clamps over the connection of the coupler and bong or bowl and prevents anything from coming loose or falling out.
What is a joint clamp for?
While a precision joint fits tightly, it can come loose during transport or when repositioning. The joint clamp mechanically secures the connection – especially when on the go or with top-heavy setups, it provides sensible protection against glass breakage.
How is it attached?
The clamp is simply slid sideways over the connected joint until it clicks into place. To separate the parts, you simply unclip it. No tools, no fuss – an inexpensive part with great benefit.

Do I absolutely need a joint clamp?
It's not essential, but it protects against parts falling out – particularly practical during transport.
