An easy to clean clamping device (10) comprises at least one clamping assembly (20, 30) having two jaws (11, 12 13, 14) providing at least one reception (71) to accommodate an element to be clamped along the longitudinal axis of said reception (71). A locking unit (40) is provided to allow closing of the jaws (11, 12 13, 14) against the force of a spring element (15) comprising a shaft (44) extending along an axis (46) and through bores (21, 22, 23, 24) of the jaws (11, 12, 13, 14) and a head (42) for operating the clamping action abutting against the uppermost jaw (11). A locking element (50) is provided having a through bore and which locking element (50) can be arranged between the head (42) and the uppermost jaw (11), wherein one portion (51) of the locking unit (40) has a larger diameter than the bore (22) of the second jaw (12) and the head of the locking unit (40) has a smaller diameter than the bore (21) of the uppermost jaw (11). The locking element (50) comprises at least one locking surface (52) which can be brought into positive locking with a corresponding surface of the head (42) for blocking removal of the locking element (50).
