Application November 13, 1941, Serial No. 418,978 1 Claim. (Cl. 173-343) The present invention relates to new and useful improvements in electrical connectors, and has for its primary object to provide, in a manner as hereinafter set forth, a device of this characshaped circular groove 23 in the wall of the bore 5 accommodates the resilient elements 8 and permits flexing thereof in opposite direction.

What is claimed is:
An electrical connector comprising a female member having a bore therein for the reception of a male member, said female member further having a substantially V-shaped, circular groove at an intermediate point in the wall of the bore, a metallic screw shell mounted on one end p'ortion of the female member, and a snap ring em bedded in the female member at an intermediate point and electrically connected to the shell, said snap ring including inwardly extending resilient elements projecting into the bore for engagement with the male member and adapted to flex in opposite directions in the groove.
