Abstract

A cylindrical housing fixed to a video card has an internal resilient insert. The insert or housing is shaped so that the housing may be pushed over and along a CRT neck with relatively low force, but requires a much higher force to remove. The insert is either an O ring or has a saw-tooth internal inner surface. Fig. 1 illustrates a cylindrical housing 1 attached to a video card 2. Housing 1 has an internal tapered portion 3 whose diameter decreases towards CRT neck 4 and into which O ring 5 is fitted. When housing 1 is pushed over CRT neck 4, O ring 5 fits closely over neck 4, a relatively low force is required. However, removal requires a much higher force as O ring 5 is forced down taper 3 to closely grip CRT neck 4.
