Abstract
Abstract A clamp for hoses or the like has an elongated band the end portions of which overlap each other and are held in overlapped relationship to form a loop around the hose or the like. Each end portion has an outwardly extending projection which can be engaged by a tool to tension the clamp. The projection on the outer end portion is a lug which is plastically deformable in a direction toward the other end portion when the maximum permissible tensioning force is reached. This ensures that the maximum permissible force cannot be exceeded and allows for a visual control as to whether or not the clamp has been properly tightened.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
100 words
A clamp for hoses and analogous commodities, comprising an elongated band having two spaced apart end portions; means for maintaining said end portions in overlapped relationship so that the band forms a loop around a commodity; and means for facilitating tensioning of said band about a commodity within the loop, including an outwardly extending projection provided on one of said end portions and being plastically deformable in response to the application of a predetermined tensioning force acting lengthwise of the band; wherein said projection and said one end portion define a junction, and further comprising reinforcing means at said junction.
Claim 2
Dependent Claim
100 words
A clamp for hoses and analogous commodities, comprising an elongated band having two spaced apart end portions; means for maintaining said end portions in overlapped relationship so that the band forms a loop around a commodity; and means for facilitating tensioning of said band about a commodity within the loop, including an outwardly extending projection provided on one of said end portions and being plastically deformable in response to the application of a predetermined tensioning force acting lengthwise of the band; wherein said projection and said one end portion define a junction, and further comprising reinforcing means at said junction.
Claim 3
Dependent Claim
15 words
A clamp as defined in claim 1, wherein said band consists of a metallic material.
Claim 4
Dependent Claim
29 words
A clamp as defined in claim 1, wherein said end portions have neighboring surfaces and at least one of said surfaces has teeth engaging the other of said surfaces.
Claim 5
Dependent Claim
16 words
A clamp as defined in claim 3, wherein said teeth extend substantially radially of said loop.
Claim 6
Dependent Claim
45 words
A clamp as defined in claim 3, wherein each of said surfaces has a set of teeth and the teeth of said sets mate with one another when the application of said tensioning force is terminated so as to maintain said band in tensioned condition.
Claim 7
Dependent Claim
22 words
A clamp as defined in claim 1, wherein said projection is a lug formed from the material of said one end portion.
Claim 8
Dependent Claim
23 words
A clamp as defined in claim 1, wherein said projection is a lug extending outwardly at an angle from said one end portion.
Claim 9
Dependent Claim
21 words
A clamp as defined in claim 1, wherein the angle between said lug and said one portion is at least 90°.
Claim 10
Dependent Claim
16 words
A clamp as defined in claim 1, wherein said reinforcing means comprises at least one rib.
Claim 11
Dependent Claim
19 words
A clamp as defined in claim 1, further comprising at least one additional projection on said one end portion.
Claim 12
Dependent Claim
25 words
A clamp as defined in claim 10, wherein said projections offer substantially identical resistance to plastic deformation in response to the application of tensioning forces.
Claim 13
Dependent Claim
43 words
A clamp as defined in claim 1, further comprising retainer means provided on the other of said end portions for retaining said projection in the proximity of said other end portion subsequent to plastic deformation resulting from the application of the tensioning force.
Claim 14
Dependent Claim
23 words
A clamp as defined in claim 12, wherein said retainer means is hook-shaped and includes sections extending radially and axially of the loop.
Claim 15
Dependent Claim
25 words
A clamp as defined in claim 12, wherein said band having two lateral edges, and said retainer means is adjacent one of said lateral edges.
Claim 16
Dependent Claim
35 words
A clamp as defined in claim 14, wherein said projection has a surface which is inclined with reference to the longitudinal direction of said band and makes an acute angle with said one lateral edge.
Claim 17
Dependent Claim
15 words
A clamp as defined in claim 1, wherein said band consists of synthetic plastic material.
Claim 18
Dependent Claim
16 words
A clamp as defined in claim 16, wherein said synthetic plastic material is glass-fiber reinforced polyamide.
Claim 19
Dependent Claim
110 words
A clamp for hoses and analogous commodities, comprising an elongated band having two spaced apart end portions; means for maintaining said end portions in overlapped relationship so that the band forms a loop around a commodity; and means for facilitating tensioning of said band about a commodity within the loop, including an outwardly extending projection provided on one of said end portions and being plastically deformable in response to the application of a predetermined tensioning force acting lengthwise of the band, further comprising additional projections provided on said one end portion, said projections offering differing degrees of resistance to plastic deformation in response to the application of tensioning forces thereto.
Claim 20
Dependent Claim
110 words
A clamp for hoses and analogous commodities, comprising an elongated band having two spaced apart end portions; means for maintaining said end portions in overlapped relationship so that the band forms a loop around a commodity; and means for facilitating tensioning of said band about a commodity within the loop, including an outwardly extending projection provided on one of said end portions and being plastically deformable in response to the application of a predetermined tensioning force acting lengthwise of the band, further comprising additional projections provided on said one end portion, said projections offering differing degrees of resistance to plastic deformation in response to the application of tensioning forces thereto.
Claim 21
Dependent Claim
19 words
A clamp as defined in claim 18, wherein at least one of said projections is provided with reinforcing means.
