A latch mechanism including a pivotable clasp biased for engagement with a catch opening in a container part. The clasp has a head portion with a cam surface of steep incline and a detent surface of slight incline, with respect to the plane of a catch support having an opening through which the clasp extends, whereby bias is easily overcome through engagement of the detent surface for latching engagement, and retention force is large, as a result of the steep angle of the cam surface. Space for lateral play of the clasp element in its receiving opening of the container, together with wedge sides of the clasp and rounded surfaces of the catch opening compensate for off-center variations therebetween upon initial container seating. Bias springs acting upon the clasp form the arms of a lateral "Y" configuration, respectively, to balance, center and stabilize the clasp upon final container seating.
