Abstract
Abstract A clamp for clamping a hose onto a nipple by means of an open band adapted to locked, with means for the contraction of the ends of the band; to that end the band is provided with perforation apertures in the upper band end and with barbs in the lower band end which engage in the perforation apertures when the band is placed about the hose; perforation apertures are also provided in the lower band end while a slot is provided in the upper band end within the area of the second-mentioned perforation apertures; the boundary wall of the slot is thereby provided within the area of its surface pointing away from the upper band end with an upset portion extending upwardly, i.e., outwardly.

Claim 4
Dependent Claim
112 words
A clamp for clamping a hose onto a nipple by means of an open band adapted to be closed, said band being provided with perforation apertures in the upper band end and with barbs in the lower band end which engage in the perforation apertures when the band is placed about the hose, further perforation apertures being also provided in the lower band end, and a slot being provided in the uPper band end within the area of the further perforation apertures, characterized in that the boundary wall of said slot is provided with an upset portion within the area of its surface pointing away from the upper end of the band.
Claim 5
Dependent Claim
16 words
A clamp according to claim 1, characterized in that said upset portion extends generally radially outwardly.
Claim 6
Dependent Claim
20 words
A clamp according to claim 2, characterized in that at least one tensional spring means is provided in the band.
Claim 7
Dependent Claim
43 words
A clamp according to claim 3, further comprising tool means for contracting the ends of the band, said tool means being constructed as strip-shaped instrument whose working end is slightly narrower than the width of the perforation apertures of the lower band end.
Claim 8
Dependent Claim
50 words
A clamp according to claim 4, characterized in that the strip-shaped instrument includes a tongue portion which is somewhat narrower than the width of the perforation apertures in the lower end of the band and wings on both sides of the tongue portion which extend perpendicularly to the strip axis.
Claim 9
Dependent Claim
28 words
A clamp according to claim 5, characterized in that the lower end of the band is provided with an upwardly bent tongue which is guided within the slot.
Claim 10
Dependent Claim
35 words
A clamp according to claim 6, characterized in that the band has a plain configuration whereby a prestress existing in the assembled condition of the clamp is produced only by elastic deformation of the hose.
Claim 11
Dependent Claim
20 words
A clamp according to claim 6, characterized in that the band includes at least one elastically deformable ear-shaped bulge means.
Claim 12
Dependent Claim
19 words
A clamp according to claim 6, characterized in that the band includes at least one contractible ear-shaped bulge means.
Claim 13
Dependent Claim
25 words
A clamp according to claim 9, characterized in that the contractible U-shaped bulge means is provided with an indentation within the area of its top.
Claim 14
Dependent Claim
23 words
A clamp according to claim 10, characterized in that the indentation has an eliptical form extending in the circumferential direction of the band.
Claim 15
Dependent Claim
