Abstract
Abstract Hose band clip with a tightening strap and a turnbuckle which is secured to one end of the tightening strap and to which a turnbuckle worm, that cooperates with gearing of the tightening strap in order to adjust the strap, is pivoted. Narrow openings are formed in longitudinal sidewalls of the housing of the turnbuckle which, when the tightening strap is tightened, are deformed by a predetermined large tension force transmitted from the worm to the housing of the turnbuckle to provide an optical indication that the tension force should not be increased any further.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
Hose band clip with a tightening strap and a turnbuckle, the turnbuckle being secured to one end of the tightening strap and having a turnbuckle worm for cooperating with gearing of the tightening strap in order to exert a tension force for adjusting the tightening strap, said turnbuckle worm being connected to a housing of the turnbuckle, wherein narrow openings are formed in longitudinal sidewalls of the housing of the turnbuckle in such a manner that deformable wall portions are formed which are subjected to a force, corresponding to said tension force, that is transmitted by said turnbuckle worm to the turnbuckle housing during said adjusting of the tightening strap, whereby, when the tightening strap is tightened to a predetermined extent, said narrow openings are deformed by deformation of said deformable wall portions due to said force which is transmitted by the turnbuckle worm to said housing of the turnbuckle to provide an optical indication that the tension force is not to be increased any further in order to prevent overloading of the turnbuckle or the tightening strap.
Claim 2
Dependent Claim
178 words
Hose band clip with a tightening strap and a turnbuckle, the turnbuckle being secured to one end of the tightening strap and having a turnbuckle worm for cooperating with gearing of the tightening strap in order to exert a tension force for adjusting the tightening strap, said turnbuckle worm being connected to a housing of the turnbuckle, wherein narrow openings are formed in longitudinal sidewalls of the housing of the turnbuckle in such a manner that deformable wall portions are formed which are subjected to a force, corresponding to said tension force, that is transmitted by said turnbuckle worm to the turnbuckle housing during said adjusting of the tightening strap, whereby, when the tightening strap is tightened to a predetermined extent, said narrow openings are deformed by deformation of said deformable wall portions due to said force which is transmitted by the turnbuckle worm to said housing of the turnbuckle to provide an optical indication that the tension force is not to be increased any further in order to prevent overloading of the turnbuckle or the tightening strap.
Claim 3
Dependent Claim
102 words
Hose band clip in accordance with claim 1, wherein the turnbuckle has a cover which rotatably carries said worm, said cover being mounted on the turnbuckle housing in such a way that it can be moved longitudinally relative thereto; wherein the cover also has tabs constructed to project laterally outwardly and extend into recesses formed in the longitudinal sidewalls of the turnbuckle housing; wherein rear vertical sides of said recesses form abutments for the tabs of the cover; and wherein said narrow openings are formed in the longitudinal sidewalls of the housing just slightly behind said rear vertical sides of the recesses.
Claim 4
Dependent Claim
45 words
Hose band clip in accordance with claim 2, wherein said cover has lateral bearing journals which extend into longitudinally elongated holes formed in the longitudinal sidewalls of the turnbuckle housing so as to enable said longitudinal movement of the cover relative to the turnbuckle housing.
Claim 5
Dependent Claim
26 words
Hose band clip in accordance with claim 2 or 3, wherein the cover is a latch type cover that is pivotally connected to the turnbuckle housing.
Claim 6
Dependent Claim
21 words
Hose band clip in accordance with claim 4, wherein said narrow openings extend transverse to the longitudinal direction of the housing.
Claim 7
Dependent Claim
25 words
Hose band clip in accordance with claim 1 or 2 or 3, wherein said narrow openings extend transverse to the longitudinal direction of the housing.
Claim 8
Dependent Claim
54 words
Hose band clip in accordance with claim 2, wherein the longitudinal sidewalls of the turnbuckle housing have deformable claw-like tabs for securing said cover in a closed position, when said worm is engaged with the gearing of the tightening strap and the tabs of the cover are positioned with the recesses of the sidewalls.
