Abstract: This device for the fluid-tight anchorage of an electric conducting cable, for example through an inlet aperture formed in a cabinet, box or the like, comprises a tubular body through which the cable is passed, such body consisting of two sections adapted to be screwed onto each other. One of these sections includes the one means such as a packing ring for sealing the cable inlet and the other section includes means such as a socket formed with radial longitudinal slots for anchoring the cable inlet. The packing ring and the socket face each other so that, when the body sections are tightened by screwing, the ring and socket engage each other, and consequently the action exerted on the ring and on the socket by their interaction is reinforced by this tightening movement.
