ABSTRACT:
Apparatus and methods for releasably retaining any one of several tubular objects of different lengths between first and second retention members provide a rod insertable into any one of said tubular objects and a carriage slidable along that rod. The lengths of the rods are grouped into a plurality of different ranges of lengths. Stepped adjustment of the position of the carriage and second retention member to any of the ranges of lengths is provided for by means of a bayonet joint arrangement having as many distinct first bayonet joint portions as there are ranges of length, and having a second bayonet joint portion common to and interfitting with each of said first bayonet joint portions and being connected to the carriage. The first and second retention members are supported on the rod and on the carriage, respectively. The supporting rod is inserted into any one of the tubular objects and the carriage on the rod is placed in stepped adjustment to the range of lengths into which the particular tubular object is grouped. The second bayonet joint portion is interfitted with the first bayonet joint portion corresponding to the particular range of lengths and the position of one of the retention members is adjusted to the length of the particular tubular object relative to the other retention member to retain that tubular object between the first and second retention members.
