The invention comprises a surgical instrument including an external tube ( 2 ) and two elongated members ( 4 ) positioned in said tube ( 2 ), each of which includes a distal end ( 10 a) for capturing one of the two tissue zones (M 1 , M 2 ) to be attached. The instrument ( 1 ) may further comprise a catching member ( 22, 25 ) for each tissue (M 1 , M 2 ) to be attached; a rod ( 15, 16 ) linked to each catching member ( 22, 25 ) enabling tension to move axially, said rod ( 15, 16 ) being separable from said catching member ( 22, 25 ) when a tension is exerted on it beyond a certain threshold; and a member ( 17 a) forming a stop for locking axially each catching member ( 22, 25 ) during said tension.
