Clamping device having a first locking mechanism with a first projection and a second projection in communication with a second locking mechanism

A clamping device, comprising:

• a housing;
• a clamping arm which is mounted so as to be pivotable in the housing;
• a first locking means which is pivotable corresponding to the pivoting movement of the clamping arm about a pivot axis of the first locking means;
• and
• a second locking means mounted in the housing which is arranged in the pivot path of the first locking means;
• wherein the first locking means and the second locking means interact in an end position of the clamping arm;
• wherein the first locking means, in the region of an end of the first locking means which is remote from the pivot axis and on a side of the first locking means facing the second locking means, comprises a recess which is defined at the side by a first projection and a second projection;
• wherein the second locking means contacts the first projection and the second projection when the clamping arm pivots into the end position and is inserted into the recess;
• wherein the first locking means comprises a first portion which receives the first projection and a second portion which receives the second projection;
• and
• wherein the first portion and the second portion of the first locking means, with the second locking means acting upon the first projection and the second projection, are movable toward one another against a spring force with the spacing between the first projection and the second projection increasing.
