Abstract
A hose clamp in which the band encircling the hose is formed on the outer segment with a step inwardly of the clamping element and with openings into which hooks of the inner segment engage. A free end of the inner segment terminates at a distance from the step which extends only over half the width of the band and any gap between the free end and the step and axially bridged by an extension of the free end of the inner segment which has a radially directed lug engaged in a longitudinal slit of the outer segment.
Claims6
A hose clamp comprising:
- a clamping band formed into a ring for encircling a hose and having an inner band end segment overlapped by an outer band end segment;
- outwardly turned retention and support hooks formed on said inner band end segment and indexingly engaging through openings formed in said outer band end segment;
- a clamping element formed on said outer band end segment for tightening said ring around said hose, whereby tension is exerted on said band by drawing said clamping element together;
- a step formed in an inner end portion of said outer segment of a height substantially equal to a thickness of the band and extending in width from one longitudinal edge of the band only over substantially half a width of said band;
- a free end formed on said inner segment and terminating at a distance from said step corresponding substantially to a length by which said clamping element is drawn together;
- and
- an extension of said band projecting beyond said free end over substantially half the width of said band adjacent and alongside said step, substantially flush with an opposite longitudinal side of said band, and of a length greater than a distance between said free end and said step, said clamping element being spanned by said inner segment along an inner side of said clamping element, said extension having a length in an untensioned state of said band which is longer than said distance by at least 1.5 times the width of said extension, said extension having a radially outwardly extending guide portion received in a longitudinal slit formed in said outer band segment and having a length at least equal to the length by which said clamping element is drawn together.
