A Jubilee Clip is a circular metal band or strip combined with a worm gear fixed to one end. It is designed to hold a soft, pliable hose onto a rigid circular pipe, or sometimes a solid spigot, of smaller diameter.

Jubilee Clips are generally made of stainless steel or galvanised or electro-plated steel. Rotating the screw has the effect of changing the diameter of the circle formed by the band. Jubilee Clips are available in a range of sizes (diameters). Larger-diameter Jubilee Clips tend to have wider bands.

In many countries, Jubilee Clips tend to be known almost exclusively by their brand name, but elsewhere (where the brand is not so well known for example), they are known by generic names such as worm drive hose clip or hose clamp or hose clip. The Jubilee Clip dominated the market to the point where the brand name is often used instead of the generic term "hose clamp", particularly in the United Kingdom, Ireland and in some of the former British Colonies. It remains the term used in everyday speech in the UK and Ireland.

The original Jubilee Clip was invented by Commander Lumley Robinson of the British Royal Navy, who was granted the first patent for the device by the London Patent Office in 1921 while operating as a sole trader. It is now subject to a registered trademark in many countries around the world. The design has been copied with many variations, and there are many other hose clips of a similar design.
