An electrical coupling for an electrical appliance such as a kettle comprises an inlet (102) in the appliance and a connector (104) for engagement in the inlet. An earth pin (116) of the inlet has a tapered end (124) and grooves (122) behind the tapered end to receive latching portions (186, 188) of springs (182, 184). A spring (192) is loaded by the earth pin (116) as the pin (116) is introduced into the connector, the latching springs (182, 184) being deflected outwardly by the tapered portions (124) of the pin until the portions (186, 188) drop into the grooves (122) to latch the connector in position. To break the connection, the connector is moved away from the inlet either axially, or pivotally, whereupon the portions (186, 188) disengage from the grooves (122), to break the latch, allowing the connector to be ejected from the inlet by the spring (192).
