Abstract
A tamper resistant cap is used in association with the plug of a quick-disconnect coupling to indicate when a socket may have been connected with the plug. The tamper resistant cap includes a frangible sidewall which surrounds the plug to prevent connection of a socket with the plug. The cap lockingly engages a seal ring groove in the plug to hold the cap in place on the plug. The only way in which the cap can be removed from the plug is by breaking the sidewall of the cap. Once the sidewall of the cap has been broken, there is a clear indication that a socket may have been connected with the plug. To promote breaking of the cap, a plurality of axially extending sections of reduced cross sectional area are formed in the sidewall of the cap. The cap is advantageously provided with an end wall which overlies the outer end face of the plug to block exposure of the plug end face to dust, dirt and other foreign particles.
