Abstract: A pipe coupling for connecting two pipe ends includes: a clamp band which has a longitudinal slot, an inner housing arranged therein, and a clamping mechanism for reducing the internal diameter of the clamp band. The clamp band is designed as a flat single piece and has an outer band portion and inner band portions which are connected to the outer band portion via at least one connection. A connection assembly is provided for securing the inner housing in the clamp band, where the connection assembly includes a first connection part and a second connection part. The first connection part extends into the second connection part, and at least one of the connection parts of the connection assembly is designed to connect the at least first outer band portion to the at least first inner band portion of the clamp band.

Abstract: A pipe coupling or a pipe clamp has an outer clamp band with an outer longitudinal slot, an inner clamp band with an inner longitudinal slot and a tensioning mechanism arranged on the outer clamp band. The inner longitudinal slot is offset in relation to the outer longitudinal slot. A separate flat spanning element is provided on the inner clamp band in order to span the inner longitudinal slot. The spanning element extends from one side of the inner longitudinal slot towards the other side of said longitudinal slot.

Abstract: A clamping belt for a pipe coupling for connecting smooth-end pipes in a force-closed manner has ends that overlap each other, where the width of the two ends of the clamping belt that overlap each other together is no more than the width of the clamping belt in the longitudinal section between the ends. A pipe coupling using the clamping belt has a sealing element and an anchoring element that surrounds the sealing element. The anchoring element includes elements that follow one another in the circumferential direction.

Abstract: A sleeve-shaped anchoring element for pipe couplings sealing pipes, with an essentially cylindrical housing and a sealing element of rubber-elastic material that is arranged in the housing. The anchoring element is arranged in the housing and has individual longitudinal supports connected to each other by means of deformable webs and having a C-shaped longitudinal section. Ends of the longitudinal supports are configured as limbs angled radially inwards. Free ends of the limbs can be brought into engagement with at least one of the pipes when the pipe coupling is clamped. Only one single web is provided between two adjacent longitudinal supports, and the two webs of a longitudinal support are arranged offset with respect to each other in the axial direction for connection to the adjacent longitudinal supports.

Abstract: A seal anchor for pipe couplings suited for frictional connection of smooth-ended pipes. The seal anchor has a housing, and at least one sealing element, for example of rubber-elastic material, arranged therein. The anchor may be of generally L-shaped cross-section and has a first limb extending in the axial direction and a second limb extending at an acute angle to the first limb. The anchoring element blank is provided with slots which run across its width in the longitudinal direction relative to the limbs and between the limbs. One or more webs span the slots to join adjacent limbs.

Abstract: A sleeve-shaped anchoring element is disclosed for pipe couplings for connecting flat-ended pipes, with an essentially cylindrical housing and at least one sealing element consisting of rubber-elastic material which is arranged in the housing. The anchoring element is arranged in the housing and consists essentially of individual longitudinal supports which are connected to each other by means of deformable webs and have a C-shaped longitudinal section. The ends of the longitudinal supports are configured as limbs which are angled radially inwards. The free ends of the limbs can be brought into engagement with at least one of the pipes when the pipe coupling is clamped. In each case only one single web is provided between two adjacent longitudinal supports. The two webs of a longitudinal support are arranged offset with respect to each other in the axial direction for connection to the adjacent longitudinal supports, seen in the circumferential direction.

Abstract: A tube coupling apparatus comprises an essentially cylindrical housing (11), for a tube coupling for connecting smooth ended tubes (16, 17), in particular, for axially strong connections with a gap (12), a one-piece molded tongue (7), bridging the gap (12), tightening straps (9, 9?) arranged to both sides of the gap (12) to accommodate closing bolts (12, 13) arranged parallel to the axis and tightening nuts (14) connected thereto, for radial tightening of the tube coupling. The housing (11) is made from flat strip material (1) and the tightening straps (9, 9?) are connected in one piece to the housing (11).

Abstract: Brace or pipe clamp with a deformable, essentially cylindrical housing, which has at least one longitudinal slot. The regions of the housing that are situated opposite one another at the longitudinal slot are formed as bent over lugs. The lugs are used to accommodate hollow bolts. The housing can be braced by means of clamping bolts, which penetrate the hollow bolts transversely and are arranged approximately tangentially to the housing, and nuts which can be connected to said clamping bolts. At least one of the clamping bolts is connected directly or indirectly with a handle for manually pretensioning the brace or pipe clamp and/or for operating the clamping bolt.
