The dental locking clasp member comprises a U-shaped piece having twin arms with substantially flat parallel opposing inner surfaces connected to an anchor portion having a plurality of anchor grooves. The twin arms have twin opposing locking recesses adjacent the free ends. Additional auxiliary parts may be part of the locking clasp member and include a bar portion with a curved spur, a receptacle portion which has locking projections which engage in the locking recesses in the case of a labial locking clasp and a clasp stem also with locking projections with a stop in the case of a buccal locking clasp. When the additional auxiliary parts are made of wax the entire locking clasp member may be used with a wax pattern to produce a completed partial casting with the appropriate locking clasp in a single casting operation which does not require reworking.
