Abstract
A hose clamp (1) comprises bands (2) forming an open ring. The ends of the open ring have band loops (3, 4) arranged around housing portions (5, 6), between which housing portions (5, 6) a clamping screw (7) with a head (8) is arranged. The bands (3, 4) adjacent to the housing portions (5, 6) have slots (9, 10). The band loop (4) along the slot (10), at least adjacent to the head (8) of the clamping screw, is turned on both sides of the slot (10) in such a manner that the distance between the band portions (11) turned adjacent to the slot (10) adjacent to the head (8) of the clamping screw is greater than the outer diameter of the head (8) of the clamping screw.
Claims16
A hose clamp, comprising:
- at least one band forming an open ring, ends of the open ring having band loops arranged around housing portions, and
- a clamping screw having a head arranged between the housing portions,
- wherein:
- the band loops adjacent to the housing portions include slots,
- one of the housing portions adjacent to the head of the clamping screw has an open recess extending transversely to a longitudinal axis of the housing portion having a width corresponding to an outer diameter of a thread of the clamping screw, to allow the clamping screw to be angled into the open recess,
- at least one of the band loops along the slot, adjacent to the head of the clamping screw, is angled upwards on both sides of the slot by a pair of parallel turned portions in such a manner that a distance between the turn portions is greater than an outer diameter of the head of the clamping screw, and
- a length of the turned portions is shorter than a length of the slot.
