ABSTRACT OF THE DISCLOSURE A strap tensioning apparatus having a U-shaped housing with two upstanding walls, each wall provided with an opening for rotatably supporting a rigid elongated bolt having a head at one end and threaded at the other end to threadedly engage a nut. A washer is secured on the bolt shank proximal to the head. Radial ratchet protrusions are coined on the washer surface and complementary ratchet engaging surfaces are formed on one wall of the U-shaped housing to provide one-way rotation of the bolt therein. A spring member may be provided between the nut and the other housing wall to exert a longitudinal force on the bolt thereby urging the ratchet members into engagement. A longitudinal slot is provided in the bolt to receive and hold a strap end as it is wound upon the bolt shank inter- mediate the housing walls. The housing may be resiliently attached to a ground anchor.
