The present invention relates to a band winding type hose clamp which is not released by vibrations or the like generated by an engine or movement of a vehicle, has a calibration function for, when the diameter of a hose is changed by aging due to long-tem use thereof, calibrating the same so as to prevent loss of the clamping force, and has a relatively simple structure. The band winding type hose clamp comprises: a body part engaged with and fixed to one end of a band; a winding part which is rotatably coupled to the body part, into which the other end of the band surrounding the outer periphery of the hose is inserted, and which is rotated by an external force to wind the other end of the band, whereby the band presses and closely contacts the outer periphery of the hose; and a cover part which is hingedly coupled to the body part spaced apart from the winding part while one end of the cover part is engaged with the winding part, and which selectively restrains the rotation of the winding part so as to maintain the elastic force of the band pressing the outer periphery of the hose.

An improved hose clamp having an annular band having an inner face, tensioning means, and an annular spring liner; the spring liner having a circumferential shoulder near an edge of the liner; and a central, cylindrical, flat contact portion of smaller circumference than the shoulder, and of smaller width than the inner face of the band. The shoulder is adapted to abut the inner face and the contact portion is adapted to contact a hose or other article to be clamped.

A pipe joint includes a joint main body comprising a nipple disposed in such a manner that a distal end is directed to one side in an axial direction and a hose clamp holding portion provided at a proximal end of the nipple and configured to be brought into abutment with an inner circumferential surface of a hose clamp which is biased in a diametrically narrowing direction so as to hold the hose clamp in a diametrically expanded state.

The present teachings include techniques for securing a connection to a dialyzer or the likee.g., securing the junction between a dialyzer port and a connector (e.g., a DIN connector) that couples the port to tubing of an extracorporeal circuit of a hemodialysis system. To this end, a locking device may engage both a DIN connector and a portion of the dialyzer, such as the cap or an adapter engaged therewith. The locking device may include an interior void sized and shaped to accommodate winged portions (or other portions) of the DIN connector to mitigate rotation thereof relative to the port to which it is engaged. Further, the locking device may be used to ensure that coupling between the DIN connector and the port is proper and secure. In this manner, a locking device can mitigate leaks, which can be catastrophic during a hemodialysis treatment or the like.

The disclosure relates to a spring clamp, having a clamp band and a positioning device for pre-positioning the spring clamp on a hose end of a hose. The positioning device having a support band and a contact region, and the support band having. The positioner having a fixing means arranged at the end of the support band, and the support band having a retainer at another end of the support band. A web is formed in the support band between the contact region and the positioner. The support band has at least two regions in the region of the positioner, the first region extending from the web away from the clamp band and the second region extending substantially perpendicularly from the first region.
