A removable cable gland includes a two-piece fitting which may be laterally assembled over a cable, as opposed to a cable being fed through an opening in the fitting. A two-piece compression nut may also be laterally assembled over the cable. The two pieces of the compression nut are slid together along a longitudinal direction of the cable by a tongue and groove arrangement. The two pieces of the fitting are plugged together in a direction perpendicular to the longitudinal direction of the cable. Once first threads of the fitting are engaged to second threads of the compression nut, the two-piece fitting is locked together by the surrounding compression nut. Simultaneously, the two-piece compression nut is locked together, such that the tongue may not slide longitudinally relative to the groove, due to the first and second thread engagement.
