Abstract: Clamping device for clamping somewhat flexible products, such as towels, comprising: a wall-mounted holder part (101) with an insertion opening (105), an operating holder part (102) with an insertion opening (106), which holder parts (101, 102) fit at least partially displaceably inside one another, and a spring member (103) which preloads the holder parts (101, 102) in a clamping position, it being possible to displace the holder parts (101, 102) with respect to one another counter to the action of the spring member (103), in such a manner that the insertion openings (105, 106) in the holder parts (101, 102) in one position at least partially correspond to one another and form a continuous insertion opening into which part of the flexible product can be inserted, in which clamping device the two holder parts (101, 102) are of essentially hollow design and together delimit an internal space, and in which clamping device one of the holder parts (101, 102) is provided with an auxiliary part (110) which is place
