A combined bicycle pump and manometric gauge for measuring the pressure in a tire or other inflatable object at any time during the inflation of the tire by simply stopping the pumping movement of the pump operator and referring to a calibrated scale. A non-return valve is located at the downstream end of the compression chamber of the pump and displaceable in a chamber provided therefor; first and second passageways bring this chamber in communication with the tire through a rapid-connecting coupler and with the manometric gauge, respectively. The manometric gauge is disposed along the pump body parallel thereto and is held in place by a casing having an aperture for viewing an index slide.
