Abrégé

The invention relates to a coupler sleeve (2) for rebars, the coupler sleeve comprising a first sleeve portion (6) which extends from a first longitudinal end (4) of the coupler sleeve (2); a second sleeve portion (7) which extends to a second longitudinal end (5) of the coupler sleeve (2); and a longitudinal passage (9). The first sleeve portion (6) has a first length (L1) which is between 30% and 70% of the total length of the coupler sleeve (2) and has a first outer peripheral surface (6.1) which narrows in the direction of the first longitudinal end (4), and the second sleeve portion (7) has a second length (L2) which is between 30% and 70% of the total length of the coupler sleeve (2) and has a second outer peripheral surface (7.1) which narrows in the direction of the second longitudinal end (5).
