A pressure spring tensioner comprises a cylindrical guiding tube having an axially elongated tube slot with a threaded spindle extended axially within the tube and rotatably mounted therein. The first sleeve is affixed to the tube adjacent an end thereof and it carries a first gripping clamp which is engageable over one end of the spring. A second sleeve assembly is slidable on the tube and it carries a second gripping clamp which engages with the opposite end of the spring. The second sleeve assembly includes a second sleeve slidable on the guiding tube and with a sliding snug fit and having a radial recess. A pad is arranged in the second sleeve in threaded engagement with the spindle and it has a radial finger extending through the tube slot which is of a length no longer than twice the thickness of the guiding tube and engages in the radial recess of the second sleeve.
