In 1959 [8] Hozelock Ltd in the United Kingdom invented and patented the international standard plastic, click-on style, push-fit hose end connector now used with garden hoses. The concept was developed to replace metal hose end connectors in coal mines, which were prone to cause static sparks and the possibility of methane gas explosions.

Hozelock Ltd was originally set up by Sydney Codling in 1959 [citation needed] to sell hoses and garden equipment including the first plastic quick-connector hose connector. . As well as manufacturing the equipment in the Haddenham factory they also designed many of their own produ
Spigots or sillcocks have male hose connectors only, and the mating end of a hose has a captive nut which fits the threads there. The thread standard for garden hose connectors in the United States, its territories, and Canada is known colloquially as "garden hose thread" (GHT), but its official designation is NH ("National Hose"):
The pilot pin is located in the centre of main contact circle on 4- and 5-pin connectors. On 3-pin (2P+E) connectors, it is located on the contact circle opposite the ground pin. The other connectors are located 105° on either side of the earth pin, rather than 120° as in the smaller variants, to make room for the pilot pin.
Twist-on wire connectors are commonly color-coded to indicate the connector size and, hence, their capacity. They are commonly used as an alternative to terminal blocks or soldering of conductors, since they are quicker to install and, unlike soldered or crimped connections, allow easy subsequent removal for future modifications.
A vampire tap (also called a piercing tap) is a device for physically connecting a station, typically a computer, to a network that used 10BASE5 cabling. This device clamped onto and "bit" into the cable [ 1 ] (hence the name " vampire "), inserting a probe through a hole drilled using a special tool through the outer shielding to contact the ...
Schematic symbols for male and female connector pins. In electrical and mechanical trades and manufacturing, each half of a pair of mating connectors or fasteners is conventionally designated as male or female, [1] a distinction referred to as its gender. [2] The female connector is generally a receptacle that receives and holds the male connector.
