A substantially cylindrical shaped metal clamp suitable for joining co-axial pipes, is disclosed and outlined. Said clamp is made from a base strap (1) which is bent in two positions rather close to its ends, one of said bends (2) developing on a non- radial axis and having the end near the other bend (3), which may be also a radial one, extending for a short straight line having an open bent end which, on locking, hooks (5) on to the non-radial bend close to the other end of the clamp. The base strap (1) forming the clamp has two wide wave (8) shaped laps which, because adjacent, give the strap an 'm' shape, said 'm'-shaped portion, which is lightened by a central lengthwise slit (9), is situated at the strap (1) end bearing the straight hooking arm (4). |
