Hi Thomas. In the USER TSConfig you can set something like this:

# Hide the delete button for all elements
options.disableDelete = 1

# Hide the delete button, but only for tt_content elements
options.disableDelete = 0
options.disableDelete.tt_content = 1

Maybe you can set it for your custom table too?
(Not sure if it disables ALL ways to delete content, as TYPO3 often has 
several ways to do the same thing..)
