Abstract
Abstract The fitting, which serves for rigid and flexible tube alike, comprises a base (1) to which two arched ribbon elements (4, 5) are hinged in a face-to-face arrangement via intermediate points along their relative external surface; the two elements (4, 5) are fastened together around the tube by causing an inward-facing lip (12), located at the end of one element (4), to engage one of a set of teeth (9) spaced apart at a given distance one from the next along the outer surface of the other element (5). The element (4) with the lip incorporates a lower section (8) shaped so as to breast, at least in part, with the cylindrical external surface of the clamped pipe or tube.

Total Claims: 8
Claim 1
Independent Claim
207 words
A clamp arrangement comprising a clamp having a base with a substantially flat inside surface, two support elements extending upwardly from said base, first and second engaging elements each having a body with an arc-shaped configuration, each said engaging element having fastening means at a first end thereof for fastening said engaging elements together, a second end of each said engaging element is free, each said engaging element is pivotally attached to one said support element at a point between said first and second ends, when an element to be clamped is inserted into the clamping arrangement said first and second engaging elements are pivotally moved about said support elements so that said free second ends of the first and second engaging elements support the element to be clamped from underneath to ensure smooth movement of the element within the clamp, whereby in the locked condition said free second ends of the first and second engaging elements engage the substantially flat inside surface of the base in such a manner that substantial gaps are defined between said free second ends and the element to be clamped, and said element to be clamped is received by the arc-shaped engaging elements and the substantially flat surface of the base.
Claim 2
Dependent Claim
207 words
A clamp arrangement comprising a clamp having a base with a substantially flat inside surface, two support elements extending upwardly from said base, first and second engaging elements each having a body with an arc-shaped configuration, each said engaging element having fastening means at a first end thereof for fastening said engaging elements together, a second end of each said engaging element is free, each said engaging element is pivotally attached to one said support element at a point between said first and second ends, when an element to be clamped is inserted into the clamping arrangement said first and second engaging elements are pivotally moved about said support elements so that said free second ends of the first and second engaging elements support the element to be clamped from underneath to ensure smooth movement of the element within the clamp, whereby in the locked condition said free second ends of the first and second engaging elements engage the substantially flat inside surface of the base in such a manner that substantial gaps are defined between said free second ends and the element to be clamped, and said element to be clamped is received by the arc-shaped engaging elements and the substantially flat surface of the base.
Claim 3
Dependent Claim
17 words
A clamp arrangement according to claim 1 wherein said element to be clamped has substantially cylindrical configuration.
Claim 4
Dependent Claim
27 words
A clamp arrangement according to claim 2 wherein in the locked condition of the arrangement said engaging elements are fastened to each other by said fastening means.
Claim 5
Dependent Claim
84 words
A clamp arrangement according to claim 2 wherein said first end of the first engaging element having an engaging lip which offsets outwardly from the body of the first engaging element to create a space to accommodate the first end of the second element, the first end of the second element having a plurality of spaced apart teeth, whereby in the locked condition of the arrangement said engaging lip engages said spaced apart teeth to keep the element to be clamped within the clamp.
Claim 6
Dependent Claim
141 words
A clamp arrangement comprising a base having a substantially flat inside surface, two support elements extending upwardly from said base, first and second engaging element each having an arc-shaped configuration, each said engaging element having fastening means at a first end thereof for fastening said engaging elements together, a second end of each said engaging element is free, each said engaging element is pivotally attached to one said support element at a point between said first and second ends, whereby in a closed condition of said clamping arrangement when said engaging elements are fastened to each other by said fastening means said free ends of the first and second engaging elements engage with the substantially flat inside surface of the base and whereby a receiving area is defined by said arc-shaped engaging elements and the substantially flat surface of the base.
Claim 7
Dependent Claim
141 words
A clamp arrangement comprising a base having a substantially flat inside surface, two support elements extending upwardly from said base, first and second engaging element each having an arc-shaped configuration, each said engaging element having fastening means at a first end thereof for fastening said engaging elements together, a second end of each said engaging element is free, each said engaging element is pivotally attached to one said support element at a point between said first and second ends, whereby in a closed condition of said clamping arrangement when said engaging elements are fastened to each other by said fastening means said free ends of the first and second engaging elements engage with the substantially flat inside surface of the base and whereby a receiving area is defined by said arc-shaped engaging elements and the substantially flat surface of the base.
Claim 8
Dependent Claim
29 words
A clamp arrangement according to claim 5 wherein said first and second engaging elements each pivotally attached to said support elements at a point on an outside surface thereof.
