A device for extracting fittings such as valves from elastomeric tubes into which they are telescoped and in which they are securely held by the resilient contraction of the tube thereabout. The valve extracting device comprises a thin-walled circular cylindrical tube which is inserted in an axial direction between the outer end of the valve and the tube and is progressively thrust therebetween. During this operation the tube is progressively freed from the valve, so that the valve may finally drop downwardly through the axial passage in the tool and thus be recovered. The elastomeric tube is then pushed off the thin-walled tubular portion of the extractor by a collar or sleeve which is slidably mounted upon the thin wall of the extractor so as to engage the outer free end of the elastomeric tube and to thrust it axially along the thin wall of the extractor.
