Zusammenfassung:	The invention relates to a band clamp including a clamping band (10) the two end portions (11, 12) of which overlap one another in the closed condition of the band clamp, the clamping band (10) comprising a tongue (13) arranged at the overlapped inner band portion (11), and a tongue recess (14) provided in the inner side of the overlapping outer band portion (12) and being complementary to the shape of the tongue (13) for receiving the tongue (13), wherein the tongue recess (14) includes two opposing side faces (lid, 14e) connected by a closed roof surface (14f ). It is proposed that the roof surface (14f) of the tongue recess (14) includes a longitudinal groove (20) and the tip portion of the tongue (13) includes a protrusion (21) configured to engage in the groove (20). L'invention se rapporte à un collier de serrage à bande comportant une bande de serrage (10) dont les deux parties d'extrémité (11, 12) se chevauchent dans l'état fermé du collier de serrage à bande, la bande de serrage (10) comprenant une languette (13) disposée au niveau de la partie de bande interne chevauchée (11), et un évidement de languette (14) disposé dans le côté interne de la partie de bande externe de chevauchement (12) et étant complémentaire de la forme de la languette (13) pour recevoir la languette (13), l'évidement de languette (14) comportant deux faces latérales opposées (couvercle, 14e) reliées par une surface de toit fermée (14f). Selon l'invention, la surface de toit (14f) de l'évidement de languette (14) comporte une rainure longitudinale (20) et la partie de pointe de la languette (13) comporte une saillie (21) conçue pour venir en prise dans la rainure (20).
