In the drawing forming part of this applition like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a perspective view of one of the sections.

Figure 2 is a similar view of the other section.

Figure 3 is a view partly in section showing the sections assembled.

Referring to the drawing in detail A and i3 represent the respective sections of the coupling, the upper and lower end portions of the respective sections being' lindicated at 10 and 11, and each having;l its opposed sides lattened. as at The section A includes a shank 13 Jrom the opposite sides of which project lugs arranged in pairs, one pair of lugs being indicated at 1% and spaced 'from the other pair of lugs 15. One side of the shank 13 is also provided with a resilient hook-like latch 16 Jfor a purpose to be hereinafter described.

The section B is hollow to receive the shank 13, the lower portion of which shank and lugs 15 being adapted to repose upon the end portion 11 of the section B. Thesection B is provided with spaced pairs of curvedlugs 1T, and lwhen the shank 13 is received by the section B, the lugs carried by said shank are arranged between the lugs 17 as clearly illustrated in the drawinof.
