Clamp with depressions in an insert

A tensioning clamp, comprising:

• a tensioning band (12), two tensioning elements (14a, 14b), a pulling element (16) and an insert (18), wherein the tensioning band (12) comprises two ends which are each folded over to form a loop (20a, 20b), wherein each of the loops (20a, 20b) receives one of the tensioning elements (14a, 14b) and has openings, the pulling element (16) connects the tensioning elements (14a, 14b) through the openings of the loops (20a, 20b), the pulling element (16) transmits a pulling force applied for tensioning the tensioning clamp (10) and pulls the tensioning elements (14a, 14b) towards each other, the insert (18) is arranged in a circumferential region of the loops (20a, 20b) between the tensioning band (12) and a material to be clamped, and the insert (18) has a profile with at least two radially inwardly projecting ribs (30a, 30b) running in the circumferential direction of the tensioning clamp (10) and a depression (32) formed between the ribs (30a, 30b), the rear side of said depression (32) facing the tensioning band (12) forming a support surface (34) for the material to be clamped;
• wherein the support surface (34) has at least one depression (40a, 40b) limited to a circumferential region lying below the tensioning elements (14a, 14b;
• wherein the insert (18) has at least one projection (42a, 42b) which engages in an opening in the tensioning band (12) in order to fix the position of the insert (18) in relation to the tensioning band (12) in the circumferential direction, wherein the opening (12) in the tensioning band is provided on an inner leg of at least one of the loops (20a, 20b).
