The pump consists of a body, on which is arranged a supply tube for the user, in which is located a non-return valve, which is mounted downstream of the supply tube. The supply tube is constructed in the form of a plug in piece (10), which fits into a tubular receptacle (11) in the body of the pump. The plug in piece is held in place by a security element (17), which bears against the body of the pump and the plug in piece locates the valve. |
