Abstract
Abstract A clamping ring is provided with a closure that is made of synthetic material and wherein the closure has catch elements into which the end of a clamping ring engages. A detachable or non-detachable closure can be used. The closure can be formed by two side members, and wherein over-lappings are avoided.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
181 words
A clamping ring fastener made of plastic with a one piece fastener head molded to one end of the clamping ring, said one end having a passage, the other end of the clamping ring having a tongue-shape, said passage permitting the tongue-shaped end to be pushed therein, saw teeth respectively disposed on the lateral edges of the tongue-shaped end and on the lateral walls of the passage for interengaging with each other; characterized in that the fastener head (4) has lateral walls (5) that are interconnected on the upper side and at the level of the base of the clamping ring (1) by spacing bars (6,7) that do not overlap, so that the saw teeth (8,9) are disposed on two lateral walls always opposite each other on the places of departure of the spacing bars, and wherein stop latches (3) are disposed on the tongue-shaped end (2) so that they are positioned at an acute angle in relation to the longitudinal axis of the clamping ring and so that they are disposed approximately at a right angle to said longitudinal axis.
Claim 2
Dependent Claim
181 words
A clamping ring fastener made of plastic with a one piece fastener head molded to one end of the clamping ring, said one end having a passage, the other end of the clamping ring having a tongue-shape, said passage permitting the tongue-shaped end to be pushed therein, saw teeth respectively disposed on the lateral edges of the tongue-shaped end and on the lateral walls of the passage for interengaging with each other; characterized in that the fastener head (4) has lateral walls (5) that are interconnected on the upper side and at the level of the base of the clamping ring (1) by spacing bars (6,7) that do not overlap, so that the saw teeth (8,9) are disposed on two lateral walls always opposite each other on the places of departure of the spacing bars, and wherein stop latches (3) are disposed on the tongue-shaped end (2) so that they are positioned at an acute angle in relation to the longitudinal axis of the clamping ring and so that they are disposed approximately at a right angle to said longitudinal axis.
Claim 3
Dependent Claim
41 words
The clamping ring as defined in claim 1 wherein under the spacing bar (7) flush with the base (12) of the clamping member (1) saw teeth (9) are provided running along the side members (5) towards the underside of the closure.
Claim 4
Dependent Claim
64 words
A clamping ring according to claim 1 characterized in that the stop latches (3) of the tongue-like end (2) are arranged spread out in an acute angle in respect to the center line (14) of the clamping ring and the tips (3) of the stop latch in the locking direction have locking faces (13) running perpendicularly to the center line of the clamping ring.
Claim 5
Dependent Claim
26 words
A clamping ring according to claim 1 characterized in that the closure member (4) is connected to the tongue-like end (2) via a U-shaped member (17).
Claim 6
Dependent Claim
31 words
A clamping ring according to claim 1 characterized in that the saw teeth (9) enter the locking space (23) and are reinforced as supporting elements (24) in the receiving space (21).
Claim 7
Dependent Claim
21 words
A clamping ring according to claim 5 characterized in that a stiffening bridge piece (10) is disposed in the member (17).
Claim 8

Claim 11
Dependent Claim
74 words
A clamping ring as defined in claim 1 characterized in that the under side (20) of the spacing bar (6) of one side is detachably connected, after an incision has been effected in one of the side members (5), the other side of the spacing bar (6) being connected to the side member (5) forming a bending edge (c-d) so that a lid capable of being bent up for locking space (23) is provided.
Claim 12
Dependent Claim
47 words
A clamping ring according to claim 1 characterized in that the member (17) has a stop (27) associated with the under side (23) of the tongue-like end (2) at the same distance from the supporting face (18) as the upper side (19) of the spacing bar (7).
Claim 13
Dependent Claim
36 words
