The invention relates to a hose clamp device (1) of a volumetric pump with a pump housing (3), on which a flap or door (4) for closing a receiving space for a flexible hose (2) is hinged, in which a hose clamp (5) is arranged that is designed to release the hose (2) laid therein when the flap or door (4) is closed and to sealingly clamp the hose (2) when the flap or door (4) is open. According tothe invention, the hose clamp (5) has a clamping bar (5) that is moveably mounted on the pump housing (3) and is spring-pretensioned in the clamping direction, which clamping bar forms on one sectiona clamping surface (5.2) that acts with a clamping jaw (3.1) that is part of the pump housing, and forms on another section an engaging surface (5.3) on which, during a closing operation, a projection(4.1) provided on the flap or door (4) slides such that a movement force is thereby applied to the clamping bar (5) counter to the spring pretension. 本发明涉及一种用于具有泵壳体(3)的容积泵的软管夹紧装置(1)，在泵壳体上铰接有用于关闭用于柔性软管(2)的接收空间的挡板或门(4)，在接收空间中设置有
