Abstract: A device for holding pipes of different diameters in a nested state comprising a plurality of engaging members each having at an intermediate portion thereof an abutting portion adapted to contact the socket end of each diametrically small pipe for restraining the small pipe from moving axially thereof, each of the engaging members being provided at least at its one end with an engaging portion fittingly engageable in an annular groove formed in the inner periphery of the socket of the diametrically largest pipe; and one or more connecting means for removably connecting the engaging members together. The holding device comprises light-weight components, is simple in construction and can be attached to nested pipes easily for holding the pipes reliably at all times.

Abstract: A device for holding nested pipes which comprises an abutting member adapted to bear against the socket ends of all the pipes, and radial-axial retainer means removably mountable on the abutting member and having an engaging projection fittingly engageable in an annular groove of the diametrically larger of two adjacent pipes included in the pipes and engaging stepped means engageable with an annular shoulder of the diametrically smaller of the two pipes. The device is composed of a small number of parts, is therefore inexpensive to make and easy to install on the pipes and reliably holds the pipes even when the two adjacent pipes differ greatly in diameter. Such devices are usable as units to provide a compact and lightweight overall holding device since a mount frame which would add to the weight of the device is not always needed.
