In a solderless electrical connector of the type comprising relatively rotatable male and female jaws having respective mounting tails adapted to be secured against a support and alignable bores adapted to receive the bared end of a conductor which is securely clamped between the jaws when they are rotated to a closed position, there is disclosed the improvements wherein the bore in the male jaw is slightly larger than the bore in the female jaw to permit the conductor to ''''bird-cage'''' when the jaws are rotated to the closed position, wherein a chamfer or countersink is added to the entrance of the bore in the female jaw for ease of insertion of the conductor thereinto, wherein the aperture in the tail of the female jaw is drilled at a slight angle therethrough, and wherein the tail of the male jaw is slightly concave to increase the area of contact between such tail and the adjacent support in the closed position of the jaws.
