Abstract: A conduit stopper used with a nozzle sealingly mounted on an elongated conduit for selectively interrupting the flow of a fluid through the conduit. The conduit has an aperture communicating with the nozzle for receiving a portion of the conduit stopper. A plug holder is connected to the linear actuator. A retainer cap is secured to the plug holder for movement therewith in the nozzle. A deformable sealing element has one end secured to the retainer cap and an opposite end is adapted to be forced into sealing engagement in the interior of the conduit to interrupt the flow of the fluid through the conduit.

Abstract: This invention relates to an improved releasable locking connector particularly adapted for use in connection with a display apparatus. The connector includes an elongated base which has one end adapted to be secured to a member of a display apparatus and the other end of the base is free. The base has a catch aperture formed on the base adjacent to the free end. A stop is formed in the base adjacent to the end adapted to be secured to a member of a display apparatus. A holding strap is formed integral with the base between the stop and the catch aperture. A catch is mounted on the base. The catch includes a resilient flat beam having one end positioned in engagement with the stop and being positioned between the strap and the base. The catch has a dog formed integral with the end of the beam opposite to the end abutting the stop. The distance from the edge of the beam abutting the stop to the dog is substantially equal to the distance from the stop to the catch aperture.
