Apparatus for connecting the locking auger sections end to end in a string of auger sections driven by an auger mining machine. Auger sections are connected end to end by inserting a shank portion of one section into a socket portion of the adjacent section and locking them by a latch bolt. The latch bolt is carried in a housing on the socket portion of one section and extends into a hole in the shank portion of the other section. The latch bolt carries a transverse locking pin and is rotatable in the housing to position the locking pin in one of two slots in the housing. One slot is of longer length axially of the bolt to permit the latch bolt to be withdrawn from the hole in the shank portion, while the other slot prevents the withdrawal of the latch bolt. The auger sections remain locked together until the latch bolt is intentionally turned to a position where the pin is in the longer slot, and the bolt is then intentionally drawn out of the shank hole.
