An apparatus for testing for the presence of leaks in sections of pipe is intended primarily for the testing of household connections. The apparatus has a front pipe sealing pad (20) to the rear wall of which (24) is attached (a) a hose so that the sealing pad can be inflated and (b) a connection (42) for a distancing rod (44). The device also incorporates a rear pipe sealing pad (22) through which are passed, properly sealed, the hose (26), tubing for expelling air (52) and a connection for filling (51). The rear pipe sealing pad can also be joined to the distancing rod (44) and is, furthermore, connected with its internal area (46) to a connection (48) so that filling and emptying can be carried out.
