<p>A wire or cable clamping device with at least one through bore (22), at least one channel (24) converging into communication with the bore, an abutment (26) at the remote end of the channel, and a wedge (27) movable along the channel between the abutment and the region of communication with the bore, is characterized in that the face (28) of the wedge (27) facing the abutment (26) is provided with an undercut groove (29), and a hole (30) is provided through the abutment for passage therethrough of a rod-like tool (31) provided with diametrically opposed projections (32) at one end for pulling engagement with the undercut groove (29) by partial rotation of the tool from an insertion position, to effect withdrawal of the wedge (27) out of gripping position with a wire or cable (23) inserted in the bore (22). Alternatively, a screw (39) may be rotatable in the hole (30) in the abutment (26), the screw having a necked tip (40) at one end rotatably engaged with the undercut groove (29) to enable the wedge to be pushed and pulled by rotation of the screw in one direction or the other, the other end of the screw being provided with means (41) for effecting rotation of the screw.</p> |
