A fluid operated contractile drive which has a contractile hose ( 4 ) extending between two head pieces ( 2 and 3 ), and attached to at least one head piece ( 2 and 3 ) by having its respective end section ( 10 ) clamped in an annular clamping gap ( 26 ) defined between clamping surfaces ( 24 and 25 ), extending in an at least partially inclined manner in relation to the longitudinal axis ( 9 ) of the contractile hose ( 4 ) of a first clamping unit ( 22 ) having a force output means ( 17 ) serving for external force output and a second clamping unit ( 23 ) able to be shifted axially in relation to the first clamping unit. In addition to the contractile hose ( 4 ) between the two clamping unit ( 22 and 23 ) there are loading means ( 45 ), effective between same, such loading means ( 45 ) acting on the clamping unit ( 22 and 23 ) to produce a reduction of the width of the clamping gap ( 26 ).
