Abstract
A firehose coupling device is provided for fixedly positioning and holding in place a set of opposed lugs on one coupling member of a firehose connection to permit quick and if desired one man coupling or uncoupling of the connection. The device includes a channel member, preferably with diverging leg portions, each leg having at least one cut out portion along the corresponding side edges of each leg so that the opposed lugs on one member are fixedly held in position and the other member may be rotated with respect to the first member.
