The ornamental design for a splitsecuritybolt with locking pin combination, as shown and described.
FIG. 1 is a front elevation view of a split security bolt with locking pin combination showing my new design including a symbolic break along the length of the article;
FIG. 2 is a top view of FIG. 1; and
FIG. 3 is a bottom view of FIG. 1; and,
FIG. 4 is a perspective view of FIG. 1 including a symbolic break along the length of the article.
The break lines and the space between them in FIGS. 1 and 4 along the article form no part of the claimed design. The broken lines and the areas within them depict portions of the split security bolt with locking pin combination that form no part of the claim.
