A hose coupling is a connector on the end of a hose to connect (or couple) it with another hose or with a tap or a hose appliance, such as an irrigation sprinkler. It is usually made of steel, brass, stainless steel, aluminium or plastic.

Due to the great variety of the designs and the number of countries in which they were created, it is difficult to trace the origin of many. Patents that cover designs similar to those below include:

A "boss" ground joint coupling valve hose coupling, primarily used for compressed air or steam. It consists of a stem, wing nut and spud. It seals as a soft copper seat located in the spud is drawn against the stem by tightening the wing nut.

Holedall (a.k.a. Mulconry, Scovill, or Rostra) dock hose couplings are built to the BS EN 1765:2004 "Rubber hose assemblies for oil suction and discharge services Specification for the assemblies", commonly known as dock hoses.

These are internally swaged hose couplings and commonly found on larger diameter fuel oil hoses used in higher pressure applications or where the hose is exposed to higher end pull, e.g., Oil Suction & Discharge (OS&D) hose). They are installed with special hydraulic ram machinery and special dies.

Holedall IX internally expanded (internally swaged) hose coupling is used in higher pressure applications, or where the hose is exposed to higher end pull, or where a full flow is required. They are installed with special hydraulic drawbar machinery, using special pull plugs.
