Jubilee clamps, pipe clips or hose locks are normally used for securing hose or tubing around an outlet under pressure.
They also serve to moderate pressures in various applications and can therefore essentially operate as a type of compression or crimp fitting. This makes them incredibly useful in applications such as automotive engine assembly, along with a wide range of household and workplace settings.
Outside of mechanical, pressure or compression tasks, they are widely regarded and used as a highly versatile fastener that can be redeployed in a wide variety of roles. As the band design is so strong - especially when made from steel, nylon or other particularly hard-wearing materials - they are often used as a sort of heavy-duty cable tie.
For example, some types of hose clamp might be found securing other sorts of ducting, components and even wiring. Many variants of pipe clips (sometimes called pipe clamps) are effectively simplified hose locks and are made to be tightened using normal screws rather than featuring a built-in worm drive system.
You will frequently see them installed on all sorts of materials and components that are being held in place along walls and ceilings, or to other mechanisms and assemblies. Typical examples include holding signs, cables or fence poles, both indoors and outdoors.
