The British type hose clamp, famously and commonly known as non-perforated band hose clamp," is a classic and globally recognized worm-drive hose clamp design. Its origins trace back to the early 20th century in the United Kingdom, and its name "Jubilee" became a proprietary eponym, much like "Hoover" for vacuum cleaners. This design is characterized by a specific, traditional construction that sets it apart from modern variations.

The core mechanism of the british type hose clamp involves three components: a galvanized or stainless steel band, a separate saddle (or housing) that holds the worm gear, and a threaded screw. The key distinguishing feature is that the band passes through this saddle, which is typically spot-welded or riveted to the band itself. The screw threads directly into this fixed saddle. When the screw is turned with a flat-head or cross-head screwdriver, it draws the band through the saddle to tighten the clamp around the hose.

This traditional design offers robust clamping force and durability. However, compared to some modern "global standard" clamps, the classic british type hose clamp often has a slightly bulkier saddle profile. The materials have evolved over time, with stainless steel versions now standard for corrosion resistance, though the classic galvanized steel version remains iconic.

It is important to note that the British hose clamp is often used generically for any worm-drive clamp in many parts of the world, especially in Commonwealth nations. However, true british type hose clamps often refer to this specific, traditional spot-welded saddle design. Its reliability has ensured its continued use across countless applications, from household plumbing and automotive repair to marine and industrial systems, cementing its status as one of the most enduring and practical fastener designs in engineering history.
