Hose Clamp for Clamping a Hose on a Pipe By Means of a Spring Band Whose End Sections in the Spread-apart State are Lockable and a Release Device for the Hose Clamp

摘要

The hose clamp secures a hose (1) to a pipe or similar and has a ring-shaped spring band (2), the end sections (3,4) of which in a widened position of the clamp are securely lockable with each other. The locking is unlockable so that the spring band can be drawn together around the hose. The end sections are arranged next to each other and are provided with teeth (5,6) in their facing edges. A device for unlocking the clamp is magnetically fitted to one end section (4) and contains an elecromagnetically operable slider together with two presence sensors which engage on the other end section (3). Only when both sensors determine the presence of a hose in the clamp is the slider operated, whereby the teeth come out of engagement.
