FIELD: construction industry.
SUBSTANCE: invention refers to devices for attachment of rubber seals on pipelines. Clamp-coupling for attachment of rubber seal on pipeline includes two similar stops with upper holes for passing of tie-bolt, one of them is main and the other is secondary representing angle iron. To main stop from its inner side guide from round stock is welded, crimping element connected to stops. To main stop from its inner side additional guide from round stock is welded. Guides are arranged in parallel and secondary stop is located on them with possibility of free movement during attachment of rubber seal on pipeline.
EFFECT: invention improves reliability of sealing of tube space between main pipeline and cover during construction of transitions - main pipelines with protective cover under water barriers and also across highways and railways.
