A principal object of this invention is the provision
of new devices which may be used to aid in the fast and
efficient installation of jet pumps in subterranean drilled
wells. Further objects include:
(1) The pro-vision of a clamping device which may
be used for installing semi-rigid ?exible tubing or pipe
in a drilled Well to prevent the tubing from binding upon
the walls of the bore hole as the tubing or pipe is lowered
into the well.

are attached to sections of semi-rigid plastic pipe which

several sizes of nipples which join the jet unit 6 to the foot
valve 8. Clamping member 22 also carries in the ring
portion 26 a set screw 42 which is used to ?x the member

The T-shaped second clamping member 24 comprises
three triangularly spaced holes 44, 46 and 4S and this
second member is split along the locus 59 of the centers
of the two holes 44 and 46, forming two second clamp
