Claim:
1. In a knee brace in which at least one of a pair of femoral arms has a length adjustment mechanism, the improvement comprising said length adjustment mechanism comprising: a slide connected to a first part of said at least one of the femoral arms, said slide having a track with pairs of detent recesses spaced along a length thereof, a receiver connected to a second part of said at least one of the femoral arms and in which said slide is displaceable in a lengthwise direction for changing the length of said at least one of the femoral arms, a detent element that is received in the track of the slide, said detent element having at least one pair of detents that is engageable in at least one pair of detent recesses for fixing a position of the first and second parts of said at least one of femoral arms relative to each other, and a toggle mechanism connected to said detent element and having a locking lever with a first position in which the at least one pair of detents is locked in engagement within said at least one pair of detent recesses, and a second position releasing said at least one pair of detents for movement out of engagement with at least one pair of detent recesses for enabling adjustment of the length of said at least one of the femoral arms, said locking lever executing an over top dead center movement from said second position into said first position so as to hold the detents against inadvertent movement out of said first position, wherein said locking lever is movable relative to said detent element and only moves said detent element in a direction toward the slide when the locking member is moved from said second position to said first position.
