Torquay have signed midfielder Iffy Allen from Yeovil Town, while free agent midfielder Danny Racchi has joined until the end of the season.
Allen, 21, only signed a one-year deal with Yeovil in the summer.
Racchi, 28, has been a free agent since leaving National League North side Tamworth in December.
"Danny is a player that first came down here three weeks ago and has done well in training," manager Kevin Nicholson told the club website.
"We didn't have the budget to be able to sign him initially but we've managed to free up some funds."
