A pin connector assembly comprising a socket ( 11 ) adapted to receive a cylindrical electrical plug ( 12 ), the plug having a central longitudinal bore ( 17 ), the socket being in the form of an insulated housing having a cylindrical receptacle ( 13 ) with a pin ( 14 ) located in the centre thereof, said pin ( 14 ) being adapted to be located in the bore ( 17 ) of the plug when the plug and the socket are in mating connection, the assembly further comprising an annular resilient collar ( 20 ) adapted to fit either over the pin ( 14 ) of the socket or within the bore ( 17 ) of the plug and which compresses radially inwards when the circumference of the bore and the pin are of essentially equal size and which remains in an expanded configuration when the circumference of the bore ( 17 ) is greater than the circumference of the pin ( 14 ), thus maintaining electrical contact between the electrical plug ( 12 ) and the socket ( 11 ).
