ABSTRACT:
A tightening ratchet for a lashing strap includes a base body having a central longitudinal direction and one end to which a first end of the lashing strap is fixed. A take-up shaft is rotatably seated on the base body for receiving a second end of the lashing strap and about which the lashing strap can be wound. A releasable tooth adjustment ratchet mechanism is operatively connected to the base body and the take-up shaft for protection against reverse turning of the take-up shaft during a winding of the lashing strap and includes: a ratchet wheel with teeth seated against relative rotation on the take-up shaft; and two ratchet slides seated longitudinally displaceable in two separate guide slits, respectively, in the base body and engaging the teeth of the ratchet wheel. The two ratchet slides are located diametrically opposite each other in relation to the ratchet wheel and have a displacement that is essentially congruent with the central longitudinal direction of the base body.
