ABSTRACT:
A quick connect-disconnect pipe coupling especially suitable for fiberglass pipelines including a male adaptor having a split ring located in a groove machined therein and bonded to one end of a pipeline. The split ring is held in the contracted position in the groove by means of a pair of restraining pins. A female sleeve is provided for receiving the male adaptor. The male adaptor is inserted into the female section, whereupon the wall of the female section "knocks out" the pins in the male section allowing the split ring to expand to its natural position and fits closely in a groove provided in the internal surface of the female section.
For disconnect the split ring is compressed by inserting a tool through the wall of the female section to recompress and close the split ring and reinserting the restraining pins. The female section is then slid over the male section.
