A strap tightener assembly (10) has a base (18), a tightening device (30) mounted on the base (18) and movable relative thereto, and a strap assembly (14) coupled to the tightening device (30). The tightening device (30) provides incremental movement of the strap assembly (14) relative to the base (18) at a plurality of predefined settings. A cover (20) extends over the strap assembly (14) and connects to the base (18) so that the base (18) and the cover (20) form a channel (44) permitting movement of the strap assembly (14) therethrough. The cover (20) defines an elongate slot (28) extending along a portion of a length of the cover (20), and the strap assembly (14) has an indicator (24, 92) identifying the relative location of the strap assembly (14) to the cover (20). A strap (20) is securable to the strap assembly (14).
