Abstract: A pipe connection includes a metal locking ring which can be pushed onto the external pipe of two interlocking metal pipes to connect the latter. The inner face of the locking ring has a leading section that tapers conically in a radial direction in opposition to the direction of application; a trailing section that tapers conically in a radial direction in opposition to the direction of application and that causes the pipe to be radially compressed, when the ring is in the locking position; and a central section lying between the leading section and the trailing section. A central section with a conical configuration improves a pipe connection of this type so that the tensile strength of heavy duty pipe connections or pipe connections consisting of pipes of material with low elasticity becomes mechanically more stable.

Abstract: A pair of manual tongs comprising two limbs which are rotatably connected in a common first rotational axis. The first limb is separated into two levers in its lever section, the two levers being rotatably connected in a first articulation, in a second rotational axis parallel to the common first rotational axis. A means of traction connects the second limb to the lever of the first limb, which is situated at a distance from the handle. The means of traction can be shortened by means of a pivotal movement of the lever of the first limb, which is situated close to the handle, above the second rotational axis. The areas of use of the manual tongs are often difficult to access. According to the invention, the second limb of the inventive manual tongs is thus separated into a lever situated at a distance from the handle and a lever situated close to the handle and the two levers are rotatably connected in a second articulation, in a third rotational axis which is parallel to the common first rotational axis.
