nonretractable
Fixed in place
Nonretractable describes something that cannot be pulled back in or withdrawn once extended.
The term applies to physical mechanisms—a nonretractable blade, nonretractable landing gear—and to abstract commitments: a nonretractable offer cannot be rescinded.
The pen has a nonretractable tip, so keep the cap on.
