There is described a dispensing pump for a fluid con- tained in a container, in which the component parts form two units which are functionally joined together by a coupling member (26), while being easily separable. The component parts of each unit are assembled together in such away as to make them hardly separable. The second unit comprises a valve (56) for communication with the container (28) and is in- separably attached to the container (28) and is further provided with a device restraining access to the valve (56), whereby this unit acts as a seal for the container. The first unit comprises a cylinder (2), piston (6), actuator means (14), spring (16) and communication means (8, 12) with the external environment and is applicable to successive second units.
