    Abstract: In a conduit connector, the tubular body has on one end spaced sections of an outer flange, and the applied cap has a peripheral wall over the one body end and an inner endshoulder opposite the flange sections on the body, while the locking gland is with its flat ring base interposed between the flange sections and the endshoulder on the body and cap, respectively, and is clamped thereto on twisting the cap into a tightened condition on the connector, with the cap being also provided on its peripheral wall with a few spaced and preferably impressed round beads which in a loose condition of the cap align with the spaces between the flange sections on the body, but on a twist of the cap into its tightened condition are moved beneath the flange sections to thereby clamp the same and the ring base of the gland thereon to the endshoulder of the cap with a crushing vice-like grip.
