  • Patent number: 5647563
    Abstract: A pipe clamp is formed of a pair of semicircular clamp halves, one having a first end region (1) and the other a second end region (2). First end region (1) has a radially outwardly extending projection (3) and two guides (6, 7) located along opposite sides. Second end region (2) has a circumferentially extending radially flexural locking strip (4) with a stop face (5) directed away from a free end of the second end region (2). In the closed position, the guides (6,7) of the first end region overlap at least a part of the second end region, so that the second end region is prevented from moving radially outwardly. In moving the first and second end regions into the closed position, the projection presses the locking strip radially outwardly until the projection (3) cooperates with the stop face (5) of the locking strip (4) in the closed position.
