Abstract: Summary
The hose clamp described herein consists of a clamping band (10) with band sections overlapping in the closed state of the hose clamp, on which hooks (12, 19) are arranged for closing the hose clamp, and with a tightening device (15) arranged in the outer band section for tightening the hose clamp around an object to be clamped. The overlapped inner end of the clamping band (10) is formed as a tongue (11) with a reduced width compared to the clamping band (10) and is received by a tongue channel (45) arranged in the outer band section. The tongue (11) is stamped out of the clamping band (10) and has outwardly projecting side flaps (42) and a bottom part (43) which is arranged between them, formed from the clamping band (10) and rises continuously from the clamping band (10) up to the height of the side flaps (42).

Abstract: The invention relates to a band clamp (10) with a clamping band (12) having an ear-like tightening device (14), an inner band end (18) having a tongue (20) extending in a longitudinal direction of the clamping band (12) and an outer band portion (22) including a recess (24), wherein the tongue (20) is configured to be inserted into the recess (24) when the tightening device (14) is being tightened.
It is proposed that the inner band end (18) includes an indicator structure (26) and the outer band portion (22) includes an opening window (28), wherein the indicator structure (26) is configured to engage with the opening window (28) and to be deformed when the tightening device (14) is being tightened.

Abstract: A compression ring made of an initially open clamping band has ends which mutually engage in puzzle-like fashion for closing the compression ring. One band end carries a tongue which projects in the longitudinal direction of the band and has arms extending transversely to the longitudinal direction of the band, and the other end of the band is formed complementarily thereto. The transverse edges of the arms, which extend transversely to the longitudinal direction of the band and face the free end of the tongue, each have a convex part at the outer end and a concave part at the inner end.

Abstract: Summary
The hose clamp described herein consists of a clamping band (10) with overlapping band sections in the closed state of the hose clamp, on which hooks (12, 19) are arranged for closing the hose clamp, and with a tightening device (15) arranged in the outer band section for tightening the hose clamp around an object to be clamped. The hooks (12, 19) are stamped out from the clamping band under cold working and each have a lug (21, 25). In the closed state of the hose clamp, the lug (21) of a hook (12) arranged on the inner band section and the lug (25) of a hook (19) arranged on the outer band section engage over each other, and the force is transmitted via transverse surfaces (27, 32) of the hooks (12, 19) that are in contact with each other.
