A tightenable band clamp with a clamping band and a tightening head with two clamping jaws which are a certain circumferential distance apart and which can be moved toward each other by a tightening device. For this purpose, at least one clamping jaw, in the area of its radially inside surface, has at least one projection which extends in the circumferential direction toward the other clamping jaw and which projects into the gap.

We claim: 1. A tightenable band clamp comprising: a clamping band; and a tightening head with two clamping jaws arranged a certain circumferential distance apart so as to form a gap, and wherein the clamping jaws can be moved toward each other by a tightening device, wherein at least one clamping jaw has, in the area of a radially inside surface thereof, at least one projection extending toward the other clamping jaw and projecting into the gap, wherein the clamping jaw is of sheet metal at least in an area of the projection, the projection being formed by a pleat, wherein the clamping jaws have cooperating projections arranged in the same axial position. 2. The band clamp according to claim 1, wherein the projection is an extension of the clamping band in the circumferential direction. 3. The band clamp according to claim 1, wherein the projection is an integral part of the clamping jaw. 4. The band clamp according to claim 1, wherein the pleat is a runner extending in the circumferential direction. 5. The band clamp according to claim 1, wherein the clamping jaw has two projections located axially on both sides of the tightening device. 6. The band clamp according to claim 1, wherein, in the area of their radially outside surfaces, the clamping jaws have initial contact zones where the jaws first come into contact with each other when the tightening device is tightened. 7. The band clamp according to claim 1, wherein the clamping band has a V-shaped cross section over at least part of a length thereof, the angle of which points radially inward. 8. The band clamp according to claim 7, wherein the cross section encloses an angle in the range of 160-176°, the V thus having a relatively large opening. 9. A pipe connection, comprising: an outer pipe; an inner pipe inserted into the outer pipe; and a band clamp tightened onto the outer pipe, wherein the outer pipe has at least two slots proceeding from an end surface thereof, and wherein the band clamp is a tightenable band clamp comprising a clamping band and a tightening head with two clamping jaws arranged a certain circumferential distance apart so as to form a gap, and wherein the clamping jaws can be moved toward each other by a tightening device, wherein at least one clamping jaw has, in the area of a radially inside surface thereof, at least one projection extending toward the other clamping jaw and projecting into the gap, the projection being formed by a pleat, wherein the clamping jaws have cooperating projections arranged in the same axial position. 10. The pipe connection according to claim 9, wherein the slots each have two walls on their circumferential sides, and where at least one slot has a bridge connecting the two side walls of the slot, the bridge being deformed into the slot when the clamp is tightened.
