A quick connect coupling includes interfitting male and female members carrying cooperable releasable coupling parts for releasably coupling the members. The coupling parts include a cooperating projection and recess dimensioned for closely fitting together when the members are interfitted in coupled relationship. The recess on one of the coupling parts is defined between relatively movable inner and outer sleeves. Each coupling part is ineffective to couple with any other coupling part lacking a properly dimensioned and located projection or recess. |
