Clamp suitable for gripping a biological sample holder, assembly consisting of a biological sample holder and suitable clamp, and treatment and/or analysis machine

The clamp comprises first and second arms (76, 78) able to move relative to one another along a gripping direction (Z) between a first position of gripping, and a first position of releasing, the first biological sample holder (10). The first arm (76) comprises a first groove (98); the second arm (78) comprises a second groove (100); when the first and second arms (76, 78) are in the first release position, the first and second grooves (98, 100) are spaced apart from one another in the gripping direction (Z); when the first and second arms (76, 78) are in the first gripping position, the first and second grooves (98, 100) are brought towards one another in the gripping direction (Z) and are face to face so as to be able to hold the lateral edges (14, 16) of the biological sample holder (10), in order to grip the biological sample holder (10) by clasping the lateral edges (14, 16) in the gripping direction (Z).
