A connector including coupling and sleeve flanges defining opposing recesses separated by an axial gap along an elongate axis. The connector also includes a arcuate bridge member radially biased outwardly against at least one of the internal contact surfaces of the opposing recesses and spanning the axial gap. The arcuate bridge member maintains electrical conductivity across the axial gap even when the sleeve does not electrically contact the coupling member. At least one of the contact surfaces defines a conical surface which is responsive to the radially biased conductive bridge member to produce a radial force against the internal contact surfaces. The radial force produces an axial force component along the elongate axis.
