ABSTRACT:
The invention relates to a coupling for pipes, tubes or hoses comprising shell portions connected by means of joint 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 a circumferential direction which engages the annular groove at a distance of at least 90.degree. before reaching the closing position. Integration of both web portions into a closed ring on the connecting flange represents a further advantage.
