A device for guiding and supporting a rod-shaped body which is advanced longitudinally through the device and which has a circular cross-section. The device comprises an outer sleeve and an inner sleeve, which is axially movable with a tight fit in the outer sleeve and is formed at one end with an internal cylindrical surface for engaging the rod-shaped body. The cylindrical surface is provided by a plurality of tongues formed by incisions in the end portion of the sleeve. At the same end the inner and outer sleeves have cooperating inclined contact surfaces, which preferably are conical with different vertical angles, and spring means are provided between the sleeves for effecting a resilient engagement between the inclined contact surfaces of the sleeves and between the internal surfaces of the tongues and the rod-shaped body. The number of tongues is preferably an odd multiple of three.
