ABSTRACT:
A quick connect/disconnect end fitting has two telescoping parts which are locked together by a wire loop which fits through diametrically opposed slots in an outer one of the parts and into a groove in the inner one of the parts. When opposing tips at the end of the loop are squeezed together, the wire loop leaves the groove to enable the two telescoping parts to be separated. An O-ring seals the space between the telescoping parts.
