ABSTRACT:
The invention relates to a device to connect hose or pipe ends. Until now such a device comprised at least two non-deformable clamp parts with flanges extending inwards which serve to press a hose end onto a nozzle or which engage behind annular collars provided at the ends of the pipes. At the ends facing one another the clamp parts are provided with a mounting arrangement for a hinge-pin which connects these parts. To avoid the work entailed by providing such a mounting arrangement and by the assembling of a number of clamp parts, it is proposed according to the invention that the clamp-type ring is made as one piece and is produced of a material which can be deformed by hand and that the flanges are formed by a permanent shaping of the ring. In this way a far more inexpensive construction is obtained, which also has the advantage of a lower mass and requires less space.
