Claim:
An electrical connection device arranged for connection to a machine cable, the device comprising: a pin and a socket, each having engagement surfaces and one of the pin and the socket having a further surface that forms a wedging surface for the device, the pin and the socket being moveable relative to each other from a released position to an engaged position in which the engagement surfaces are engaged to form an electrical contact, at least one engagement surface comprising a convexly curved surface, and a wedge portion arranged to impart a force on the wedging surface on movement to the engaged position, the wedge portion comprising a flexible material, wherein the pin and the socket are arranged so that the engagement surfaces move into opposing relationship on movement to the engaged position and the force imparted on the wedging surface biases one of the opposing engagement surfaces against the other engagement surface in a manner such that the engagement surfaces frictionally engage with one another.
