A security closure system for terminating the hose-connector connected to the outlet of a storage tank whose contents are to be periodically pumped out. A first male-outlet component is provided with an outer, circumferential annual groove for reception therein of camming elements of camming arms, and has a terminal projecting tongue provided with an opening or hole for receiving a locking device, such as a padlock. The male-component is further provided with an enlarged mounting flange for mounting the male-component to a wall of the storage tank or to a bulkhead adjacent the storage tank. The security closure system also comprises a second female part, which is a female closure cap that matingly receives therein the first male-component. The closure cap has a slot for passing therethrough the tongue of the first male-component, whereby a padlock or other lock may be used for locking the cap in place over the first male-component. The closure cap is also provided with a pair of parallel, upstanding partitions or walls sandwiching therebetween the projecting tongue of the first male-component protruding through the slot of the closure cap. These partitions project a sufficient height above, and extend a sufficient length along, the protruding tongue so as to prevent access thereto and to the locking device inserted through the opening of the tongue, whereby access thereto is denied and the tampering thereof via saws, and the like, is prevented. Additional pins or rods are provided for additional tamper-proof resistance to cutting.
