Open the CIPO recordAbstract From the Canadian patent
The invention relates to a coupling for pipes tubes or hoses comprising shell portions connected by means of joints bolts and also comprising a bolt lever locking mechanism. Substantial improvement is obtained by the fact that the concerned web portion is part of an outer guide flange extending in circumferential direction which engages said annular groove at a distance of at least 90° before reaching the closing position. Integration of both web portions into a closed ring on the connecting flange represents further advantage.
