Device for connecting e.g. vacuum hoses, utilized for conveying e.g. sand, has coupling unit that is provided for attaching hoses, and clamping devices provided for tensioning hoses with coupling unit

摘要

The device has a coupling unit (4) on which hoses (1, 2) are attached, where the coupling unit is a hollow cylindrical body. Clamping devices (18, 19) are provided for tensioning the hoses with the coupling unit, where the devices include a locking force producing unit (22) i.e. lever arrangement (23), for producing locking force, and a locking force transferring unit (9) e.g. rope, for transferring locking force to a lateral surface (MS) of the hoses. The lever arrangement includes a handle (3) and a latch (24), where handle is rotatably connected with the latch around a rotation axis (25).
