The connection strip is for use with a dual-purpose hot water and central heating boiler. The strip comprises four modules made of molded hard plastic and assembled side-by-side by being mutually juxtaposed with tie bars passing through them, the modules being respectively associated with outgoing heating water, outgoing domestic hot water, incoming cold water, and returned heating water, each module including the corresponding stopcocks and ducts together with lengths of a short-circuit duct enabling the modules to co-operate to form a short-circuit on the heating circuit, suitable for feeding water to said heating circuits and for enabling leak tests to be performed when the boiler is not present.
