Abstract
A female quick disconnect coupling includes a locking mechanism which requires different forces to connect and disconnect a male coupling. A tubular housing is slidably mounted within a sleeve, and a pair of coil springs are mounted between the housing and the sleeve. Only one of the springs is compressed as the housing moves in one direction within the sleeve to permit a male coupling to be connected to the female coupling. Both springs are compressed as the housing moves in the other direction to permit the male coupling to be disconnected, thereby requiring a relatively high force to disconnect the couplings.
